A car, starting from rest, accelerates at the rate (f) through a distance (S), then continues at constant speed for some time (t) and then decelerates at the rate ` f//2` to come to rest. If the total distance is ` 5 S`, then prove that
` S=1/2/ ft^(2)`.

A

`s=(1)/(72)ft^(2)`

B

`s=(1)/(36)ft^(2)`

C

`s=(1)/(2)ft^(2)`

D

`s=(1)/(4)ft^(2)`

A bike starts from rest and accelerates at 4 m//s^(2) for 5.0 s. It then moves at contant velocity for 25.0s, and then decelerates at 2.0 m//s^(2) unit it stops. Find the total distance that the motorcycle has moved.

A car starting from rest is acceleration at constant rate until it attains a speed of 12 m/s. It moves with the constant speed 12 m/s for some time and then it is retarded at other constant rate until it comes to rest.
