kinetic energy

A neutron in a nuclear reactor makes an elastic head-on collision with the nucleus of a uranium atom initially at rest. (a) What fraction of the neutron's kinetic energy is transferred to the uranium nucleus? (The mass of the uranium nucleus is about 238 times the mass of the neutron.) (b) If the initial kinetic energy of the neutron is 1.6 10-13 J, find its final kinetic energy and the kinetic energy of the uranium nucleus after the collision. J (neutron) J (carbon nucleus)

recoil veelocity

A 37.0 kg child standing on a frozen pond throws a 0.500 kg stone to the east with a speed of 6.00 m/s. Ignoring friction between the child and the ice, find the recoil velocity of the child. (Assume the positive direction is to the east.) m/s

momentum

A 0.300 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.200 kg puck moving initially along the x axis with a speed of 2.00 m/s. After the collision, the 0.200 kg puck has a speed of 1.00 m/s at an angle of = 54.0° to the positive x axis (Fig. 8.10). Figure 8.10. (a) Determine the speed of the 0.300 kg puck after the collision. m/s (b) Find the fraction of kinetic energy lost in the collision.

2. [SJ3 8.P.047.] Tarzan, whose mass is 75.0 kg, swings from a 3.00 m vine that is horizontal when he starts. At the bottom of his arc, he picks up 55.0 kg Jane in a perfectly inelastic collision. What is the height of the highest tree limb they can reach on their upward swing? m
