Question

A particle starts from the rest with acceleration 4 metre per second square at reachest to velocity 54 kilometre per hour find the time taken by the particle​

Answer 1

Given

Acceleration=4m/s^2

Final velocity = 54 km/HR= 15m/s

Initial velocity= 0

We know that,

V=u + at

15= 0 + 4 * t

15 = 4*t

t= 15/4=3.75 s
