Question

A particle moves in a straight line with a retardation of 10metre per second square . If the initial velocity is 50metre per second when it will stop

Answer 1

Answer:

Acceleration = -10m/s²

Initial velocity = 50m/s

Final velocity = 0m/s (as particle is stopped)

Time = ?

First equation of motion , v=u+at

0=50+(-10)×t

10t=50

t=5 second

The particle will stop after 5 second.
