Question

a person starts motion in a straight line at a velocity of 15m/a his velocity is changing at a constant rate if he stops after 75 seconds what is his accelaration​

Answer 1

Given:

Initial velocity=15m/s

Final velocity=0m/s

Time=75s

To Find:

deceleration

Solution:

Acceleration= v-u÷t

= 0-15÷75= -0.2

Therefore the acceleration is -0.2 m/s
