A train is traveling with a velocity of 72 km/h. The breaks are applied to retard the motion of the train uniformly. If the train stops after traveling 50 meters away from the place where the breaks were applied, find the retardation of the train.
A car starts from rest and accelerates uniformly at the rate of 1 m/s^2 for 5 seconds. It then maintains constant velocity for 30 seconds. Then breaks are applied and the car is uniformly retarded to rest in 10 seconds. Find the maximum velocity attained by the car. Also find the distance traveled by the car.
A car is moving with a uniform velocity of 10 m/s. The driver of the car decided to overtake a bus moving ahead of the car. So he accelerates the car at 1m/s^2 for 16 seconds. Find the velocity of the car at the end of 10 seconds.Also find the distance traveled by the car by accelerating.
A circular cycle track has circumference of 314m with AB as one of its diameter.A cyclist travel from A to B with a velocity of constant magnitude 15.7 m/s.Find (a). The distance traveled by the cyclist. (b). The displacement of the cyclist. (c). Average velocity of the cyclist.
