The car is moving with constant velocity (so, constant speed in a straight line)
Explanation:
Acceleration is defined as the rate of change of velocity:
where
is the change in velocity of the object
is the time taken for the velocity of the object to change by
In this problem, we have car moving with an acceleration of
This implies that
So, the velocity of the object is constant. However, velocity is a vector quantity: so it has both a magnitude (the speed) and a direction. Since the velocity here is constant, this means that both the speed and the direction must be constant: and this is possible only if the car is moving with constant speed in a straight line.

Answer:
Elastic potential energy = 5.04 J
Explanation:
Given that
Extension e = 18 cm = 0.18 m
Force F = 56N
Elastic potential energy = 1/2Fe
Elastic Potential energy = 1/2 ×56×0.18
Elastic potential energy = 5.04 J
