Question

A particle is initially at rest and starts with an acceleration of 2 metre per second square then find the velocity of the particle at t is equals to 2 second​

Answer 1

u = 0m/s

a = 2m/s^2

t= 2 sec

v = u + at

= 0 + 2*2

= 4m/s

Answer 2

Answer:

Explanation:

as particle is initially at rest

so,

u=0 m/s

given, a=2m/s² and t=2 sec

using first eq of motion,

v=u+at

v=0+2×2

v=4m/s
