A car travelling with a velocity of 80 km/h slowed down to 44 km/h in 15 s. The retardation is

A car travelling with a velocity of 80 km/h slowed down to 44 km/h in 15 s. The retardation is

A car is traveling at a velocity of 10 km/h on a straight road. The driver of the car throws a ball. If the ball is to reach back to the driver, the direction of throw makes the following angle with the direction of the car:

A toy car initially moving with uniform velocity of 18 "km h"^(-1) comes to a stop in 2 s. Find the retardation of the car in S.I. units.

A motorcar of mass 1200kg is moving along a straight line with a uniform velocity of 90 km//h . Its velocity is slowed down to 18 km//h in 4s by an unbalanced external force. Calculate the acceleration and change in momentum. Also, calculate the magnitude of the force required.

A passenger sitting by the window of a train moving with a velocity of 72 km/h observes for 10 seconds that a train moving with a velocity of 32.4 km/h completely passes by it in 10 seconds. The lengthof the second train is

A motorcylcle is moving with a velocity 80km/hr ahead of a car moving with a velocity of 65 km/hr in the same direction. What is the relative velocity of the motorcyle with respect ot the car:-

A car moving with a velocity of 40 km/h can be stopped by brekes after travelling at least 5 m. If same car moves at a speed of 80 km/h the minimum stopping distance is

A car travels with a uniform velocity of 25 m s^(-1) for 5 s. The brakes are then applied and the car is uniformly retarded and comes to rest in further 10 s. Find : (i) the distance which the car travels before the brakes are applied, (ii) the retardation,and (iii) the distance travelled by the car after applying the brakes.

A car is travelling at a velocity "10 km h"^(-1) on a straight road. The driver of the car throws a parcel with a velocity 10sqrt2km h^(-1) with respect to the car, when the car is passing by a man standing on the side of the road. If the parcel is to reach the man, the direction of throw makes the following angle with the direction of motion of the car
