[00:00:03]Welcome back to Academy of Motion.

[00:00:20]Yeah. Group science next.

[00:01:02]question.

[00:01:04]First question.

[00:01:22]A car starts from rest runs for 2 minutes with an uniform acceleration of 1 m/s squared. Find the speed obtained by a car.

[00:01:44]First equation equation equation b = u + a t v + u v v = u + a equation equation v² = u ² + 2 a s equation v = u + a t v² = u ² + 2 a s = u t +/ a t² square.

[00:02:36]Initial velocity.

[00:02:50]starting.

[00:02:51]Okay.

[00:03:02]Final velocity Vality.

[00:03:16]Okay.

[00:03:18]for distance.

[00:03:43]First question.

[00:03:46]First question. car 1 m square= 1 m² okay time t = 2 minutes.

[00:04:18]Second 120 m per second. 120 uh minute. 122nd.

[00:04:45]Okay, sorry. 1202 order value 1202.

[00:05:07]Starting velocity. Start.

[00:05:14]for 2 minutes.

[00:05:38]For the Answer U order value zero plus A value 1 m/s² B= U + V 120 m per second. Answer me per second.

[00:06:43]com.

[00:06:51]Next question.

[00:07:02]Kilome per kilometer per hour. Okay.

[00:07:05]Kilome per hour.

[00:07:27]Starting from rest. Starting from rest.

[00:07:30]A train attain a speed of 90 km per hour in 5 minutes. Assuming that the acceleration is same, then the distance traveled by a train at the same time will be and the time train.

[00:07:52]Okay.

[00:07:59]Tal 5 minutes.

[00:08:11]Okay.

[00:08:15]Second.

[00:08:25]Okay. Time 300 second. Okay. Next hour.

[00:08:44]Okay.

[00:08:48]0.

[00:08:53]U= 0.

[00:08:58]Velocity final velocity V= 90 kilome per hour. Kilome per hour me second kilome hour 5 by 18 90 into 5 by 18 m/s 10 m/ second 10 m/s. 10 m/s and distance. Speed time distance 10 18 by hour 18 by 5 by 18 by 18 90 km per hour. 90 foreign.

[00:11:01]Okay.

[00:11:16]5 by 18 by 18. Okay.

[00:11:26]18.

[00:11:28]Okay.

[00:11:39]distance for the equation. S equal to S = U T +/ A B²= U² + 2 A velocity difference.

[00:12:49]Final velocity 25 m/ second.

[00:12:53]Acceleration difference 25us vus uid second.

[00:13:14]Okay. m/s 25 m/s final velocity minus initial velocity divided by time. Okay.

[00:13:28]Yes.

[00:13:32]UT 300 plus half a A value 25 by 300 25 by 300 in T² T T value 300 300 into 300 T² 300.

[00:14:04]Okay.

[00:14:05]25.

[00:14:13]Okay.

[00:14:18]Two two Fore question.

[00:14:52]Okay, next question. Car running at the uniform acceleration speed.

[00:15:05]Can find the distance traveled by a car at this time.

[00:15:20]Okay.

[00:15:24]peri.

[00:15:43]A car is running at the uniform acceleration of 1 m/s squared. in 5 seconds at a speed of 5 m/s squared to 10 m/s. 10 m/s. 5 m/s to 10 m/s. Find the distance traveled by a car at this time.

[00:16:05]1 m².

[00:16:08]Initial velocity 5 m/s. U 5 m/ second. V 10 m/ second. 10 m per second.

[00:16:30]Okay.

[00:16:40]T= 5 second. Okay.

[00:16:47]S = UT² + S = UT² +/ A T² UT +/ A² UT +/ A² UT² S = U +/ A² Okay, value.

[00:17:19]U five plus half a order value 1 into a t² t value 5 into 5 25. Okay.

[00:17:45]/ 2 / 2 answer 37.5.

[00:18:06]Okay. 37.5 m. Next question. Next question.

[00:18:30]R me per square brake.

[00:18:49]A brake applied to a car produce an acceleration of 6 m/s squared in opposite direction of the motion. If the car take 2 seconds to stop after application of brake, calculate the distance traveled during this time.

[00:19:17]- 6 m/s square - 6 m/s square.

[00:19:32]Okay.

[00:19:37]2 second final velocity velocity zero. Final velocity zero in the 2 second time.

[00:20:05]S= A square= U for V = V V² = U² + 2 A S.

[00:20:31]Okay. for B= U + A for B = B = U + A E B = U + A T U plus A A - 6 in T 2 U= 12 m per second.

[00:21:45]A t² value. Okay.

[00:22:03]Rend second into 2 +/ a t²/ a value - 6 t² t value 2 into 2 4 okay 24us 12 m distance First V= U +.

[00:23:00]Okay.

[00:23:01]in the question.

[00:23:13]Okay.

[00:23:25]When one box is let fall from a tower, it take 4 seconds.

[00:23:31]4 seconds to reach the ground. Determine the distance traveled by a box.

[00:23:39]Time= 4 second initial velocity.

[00:23:53]Starting in velocity acceleration 9 81 m per second square.

[00:24:29]9.8 9.8.

[00:24:45]Okay. 9.81 81.8.8 question.

[00:24:55]Okay.

[00:25:03]S = S = U T. S = U T +/ A T².

[00:25:18]Okay.

[00:25:21]U² 9.81 value 4 into 4. Okay.

[00:25:41]4 2 into 4 8 9 9.81 78 78.48 48 answer 8 78.48 m.

[00:26:32]A car accelerated uniformly from 18 kmbh to 72 kmbh in 5 seconds. The acceleration of this car is dash car.

[00:26:46]Okay.

[00:27:07]18. Okay. 18 km per hour 18 by 18 second. hands.

[00:27:27]Val 72 km/h. Final velocity 72 km/ hour 72 by 18.

[00:27:52]20 m per second.

[00:28:00]Five second difference.

[00:28:17]Final velocity 20 20 minus 5 divided by time time value 5 / 5 = 15 / 5 = 3 m per sec 3 second answer 15 3 second Oh, sorry. Sorry. 3 m/s square 3 m/ second square. Sorry. Acceleration.

[00:29:05]Acceleration.

[00:29:08]Final velocity minus initial velocity.

[00:29:22]answer question.

[00:29:49]Next group like comfort.

[00:30:44]Next video.

[00:30:47]Bye.
