Question

A car having an acceleration of 20m/s2 was initially at rest but after some time the velocity increased.The time taken by the car is 5 sec. Find the final velocity !!!!pls solve it step by step.!!​

Answer 1

Answer:

100 m/s

Explanation:

$Using\ equation\ of\ motion\\v = u+at\\v=final\ velocity\\u=initial\ velocity\\a=acceleration\\t=time\ taken\\Now\ putting\ values\\v =\ ?\\u=0\ m/s\ (As\ initially\ at\ rest)\\a=20\ m/s^2\\t=5\ sec\\v = 0+20*5=100\ m/s$

Therefore final velocity = 10 m/s
