A man of mass M =58 kg jumps from an aeroplane as shown in Fig. He sees the hard ground below him and a lake at a distance d = 1 m from the point directly below him. He immediately puts off his jacket (mass m =2 kg) and throws it in a direction directly away from the lake. If he just fails to strike the ground, find the distance (in 101m) he should walk now to pick his jacket. (Neglect air resistance and take the velocity of man at the time of jump with respect to earth zero.)

A strip of wood mass M and length l is placed on a smooth horizontal surface. An insect of mass m starts from rest at one end of the strip and walks to the other end in time t ,
moving with a constant speed. The speed of the insect as seen from the ground is ,
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 VB and VA, respectively, find the ratio of 6 VB and 5 vA.

A massless spring of force constant 1000 N m/s is compressed a distance of 20 cm between discs of 8 kg and 2 kg, spring is not attached to discs. The system is given an initial velocity 3 m/s perpendicular to length of spring as shown in the figure. What is ground frame velocity of 2 kg block (in m/s) when spring regains its natural length.

A frog sits on the end pf a long boord of length L = 5 m. the boord rests on a fricationless horizontal table. The frog wants os the minimum takes – off speed i.e relative to ground v that allows the frog yo do the trick? The board and the frog have equal masses.

Figure shows a wedge A of mass 6 m smooth semicircular groove of radius a = 8.4 m placed on a smooth horizontal surface. A small block B of mass m is released from a position in groove where its radius is horizontal. Find the speed (in m/s) of bigger block when smaller block reaches its bottom most position.
