A man and a cart move towards each other. The man weighs 64 kg and the cart weighs 32kg. The velocity of the man is 5.4 km/hr and that of the cart is 1.8 km/hr. When the man approaches the cart, he jumps on to it. The velocity of the cart carrying the man will be

A

3 km/hr

B

30 km/hr

C

1.8 km/hr

D

zero

Text Solution

Verified by Experts

The correct Answer is:

A man and a cart move towards each other. The man weight 64kg and the cart weighs 32kg . The velocity of the man is 5.4km//hr and that of the cart he jumps on to it The velocity of the cart carrying the man will be .

A man weighing 60kg runs along the rails with a velocity of 18km//h and jumps into a car of mass 10 quintal standing on the rails. Calculate the velocity with which the car will start travelling on the rails .

A cart is moving with a velocity 20m/s. Sand is being dropped into the cart at the rate of 50 kg/min. The force required to move the cart with constant velocity will be :-

In the figure shown a cart moves on a smooth horizontal surface due to an external constant force of magnitude F . The initial mass of the cart is M_(0) and velocity is zero. Sand falls on to the cart with negligible velocity at constant rate mu kg//s and sticks to the cart. The velocity of the cart at time t is :

A man weighing 60kg runs along the rails with a velocity of 8km//h and jumps into a car of mass 1 quintal standing on the rails. Calculaate the velocity with which car will start travelling along the rails.

A child of mass 4 kg jumps from cart B to cart A and then immediately back to cart B . The mass of each cart is 20 kg and they are initially at rest. In both the cases the child jumps at 6 m//s relative to the cart. If the cart moves along the same line with negligible friction with the final velocities of V_(B) and V_(A) , respectively, find the ratio of 6V_(B) and 5v_(A) .
