The car acceleration is 25 km/hr/s
Acceleration is the rate of change of velocity with respect to time. Acceleration is given by:
Acceleration = change in velocity/time
Newton's law of motion is given by:
v = u + at
Where v is the final velocity = 100 km/h, u is the initial velocity = 0 km/h, t is the time = 4s, a is the acceleration.
v = u + at
100 = 0 + 4a
a = 25 km/hr/s
Hence the car acceleration is 25 km/hr/s
