Give the magnitude and direction of the net force acting on a stone of mass 0.1kg:- lying on the floor of a train which is accelerating with `1 m s^-2`, the stone being at rest relative to the train.Neglect air resistance throughout.

Give the magnitude and direction of the net force acting on a stone of mass 0.1kg:- just after it is dropped from the window of a train accelerating with 1m s^-2 , Neglect air resistance throughout.

Give the magnitude and direction of the net force acting on a stone of mass 0.1kg:- just after it is dropped from the window of a stationary train, Neglect air resistance throughout.

Give the magnitude and direction of the net force acting on a stone of mass 0.1kg:- just after it is dropped from the window of a train running at a constant velocity of 36 km//h , Neglect air resistance throughout.

A rocket with a lift-off mass 20,000 kg is blasted upwards with an initial acceleration of 5.0 m s^-2 . Calculate the initial thrust (force) of the blast.

Figure 5.18 shows a man standing stationary with respect to a horizontal conveyor belt that is accelerating with 1 m s^-2 . What is the net force on the man? If the coefficient of static friction between the man’s shoes and the belt is 0.2, up to what acceleration of the belt can the man continue to be stationary relative to the belt ? (Mass of the man = 65 kg.)
