Two bodies make an elastic head on colision on a smooth horizontal table kept in a car.Do you expect a change in the result if the car is accelerated on a horizontal road because of the noninertial character of the frame? Does the equation velocityof separation = velocity of approach remain valid in n accelerating car? Does the equation final momentum =initial momentum remain valid in the accelerating car?

A collision experiment is done on a horizontal table kept in an elevator. Do you expect a change in the results if the elevator is accelerated up or down because of the noninertial character of the frame?

A car weighing 1600 kg moving with a velocity of 30 m/s retards uniformly coming to rest in 20 seconds. Calculate the (i) Initial and final momentum of the car. (ii) Rate of change of momentum of the car. (iii) Acceleration of the car.

Two cars A and B of equal masses (100 Kg) are moving on a straight horizontal road with same velocity 3m//s as shown. At t = 0 car A starts accelerating with constant acceleration of 2 m//s^(2) (intial separation between car is 25 m ). Choose correct options (neglect length of cars)

A bob suspended from the ceiling of a car which is accelerating on a horizontal road. The bob stays t rest with respect to the car with the strig making an angle theta with the vertical.The linear momentuym of the bob as seen from the road is increasing with momentum? If not, where is the external force which changes the linear momentum?

The device in figure is an acceleraometer which is fitted to a car. It consist of a spherical ball, mass 0.08 kg, attached to a pointer which can move horizontally against a fixed scale that gives the acceleration of the car, O indicates zero acceleration. On each side of the ball are attached identical springs, S_(1) and S_(2) . that are fixed at their ends. The device is enclosed in a rigid transparent housing. The car accelerates towards A. If the car starts from rest at time t=0 and travels along a straight road. The accelerometer readings are recorded in table. {:("Time//s","Acceleration//ms^(2)"),(0.00-3.00,11.00),(3.00-4.50,7.00),(4.50-7.00,0.00):} How far does the car travel in the first 7.00s?

STATEMENT-1 : Two bodies of mass M and 2M released from rest and they move towards each other due to their mutual gravitational force of attraction and collide at mid point. STATEMENT-2 : If the total mechanical energy of a body is zero than its linear momentum is necessarily non zero at any point other than reference point. STATEMENT-3 : The linear momentum of the bob of a simple pendulum suspended by the roof of a car accelerating on a horizontal road increases due to tension in the string of the pendulum.
