Question
A vehicle moving at a speed of 24 m/s accelerates to 56 m/s in 4 s. The acceleration of the vehicle is ___ m/s2.
Hint:
8 m/s²
The correct answer is: 8
Given that,
The initial velocity, u = 24 m/s
The final velocity, v = 56 m/s
Time taken, t = 4 s
On using the first equation of motion we get,
v = u + at
Or, a = (v – u)/t
Or, a = (56 - 24)/4
Or, a = 32 / 4
Or, a = 8 m/s2
Therefore, the acceleration of the vehicle is 8 m/s2.

An object starts from rest. It means that _____.
Rest implies that the body was stationary with respect to the ground. Any body which doesn't move has zero velocity, since it doesn't covers any distance. Thus, any body starting from rest has initial velocity= zero.
