Question

if a body starts from rest and then moves with speed of 10m/s find acceleration of body in 2 second​

Answer 1

Answer:

Given,

u = 0m/s

v=10m/s

t= 2 second

a = ?

we know that v=u+at

put the value of u,v and t in this equation

10= 0+ a× 2

10 = 2a

a = 5 m/s^2

Hence, acceleration of body is 5 m/s^2.

Answer 2

Answer:

a = v - u / t

where , a = acceleration

v = final velocity

u = initial velocity

t = time

= 10 m/s - 0m/s / 2s

= 5m/s^2
