Question

If a scooter is moving with velocity 20 m/sec and get acceleration of 3.5 m/sec2 find the value of time of getting this velocity if in that time velocity is 40 m/sec.​

Answer 1

Answer:

ANSWER is 1.75s

Explanation:

Here :- initial velocity (u) = 20m/s

acceleration = 3.5 m/s^2

final velocity (v) = 40 m/s

time taken = ???

A/Q we have to use 1st kinamatical equation

v = u+ at

or t = u+a / v

putting values t = 20m/s + 3.5 m/s^2 / 40 m/s

= 1.75 second .......
