Initial velocity u = 0
Final velocity v = 203 km / h
= 203 x 1000 m / 3600 s
= 56.388 m / s
Distance S = 2000 m
From the relation v 2 - u 2 = 2aS
Accleration a = [ v 2 - u 2 ] / 2S
= 0.7949 m / s 2
What is Accleration?
Compared to displacement and velocity, acceleration is like a raging fire-breathing dragon of motion variables. it can be violent. Some people fear it. And when it's big, you have to be careful. Taking off an airplane, braking a car, cornering a go-kart at high speed are all sensations of acceleration.
Acceleration is the name we give to any process that changes velocity. Velocity is speed and direction, so there are only two ways to accelerate. Either change speed, change direction, or change both.
Therefore, the acceleration is: 0.7949 m / s 2
