A vehicle starts from rest with a uniform acceleration until a velocity of 48 km/h is reached. It then moves with a constant speed until it decelerates and finally stops 600 m from the starting point. The whole journey takes 1 minute, and the magnitude of the deceleration is twice that of the acceleration. Calculate: The time (in seconds) it takes the vehicle to reach a velocity of 48 km/h.
The time (in seconds) the vehicle moves with a constant speed.
The time (in seconds) it takes the vehicle to decelerate and stop.
The acceleration of the vehicle (give your answer in m/s2).
The distance the vehicle travels with constant velocity (give your answer in m)/
