Question

Velocity of a body changes from 2 m/s to 6 m/s in 2 s.What is the acceleration of the bodya.
6 m/s2

b. 2 m/s2

c. 10 m/s2

d. 8 m/s2​

Answer 1

Answer:

Option b

Explanation:

Initial velocity(u) = 2 m/s

Final velocity(v) = 6 m/s

Time taken to do it(t) = 2 sec

Acceleration(a) = a m/s²

According to formula,

a = ( v - u ) / t

=> a = ( 6 - 2 ) / 2

=> a = 4 / 2

=> a = 2

So acceleration = a m/s² = 2 m/s²

So, option b is the correct option.

Hope it helps you =)

Have a great day!!!
