Question

a particle is moving on straight line with retartdation of 2m/s^2. if initial velocity of particle is 11m/s. the dispalcement of particle will be

Answer 1

Given:

u = 11m/s

v = 0m/s (Particle finally comes to rest due to retardation.)

a = -2m/s^2

s = ?

Answer:

2as = v^2 - u^2

s = 0 - 121/2*-2

= 30.25m
