A lighter block and a heavier block sit on a frictionless surface. Please answer the following questions about the final momenta anc kinetic energies of the blocks for the given situations. Both blocks are initially at rest. The same force F then pushes to the right on each block for 1 meter. Which block has the larger final kinetic energy after the force acts? lighter same heavier O insufficient information Submit Answer Tries 0/2 Which block has the larger final momentum after the force acts? lighter same heavier insufficient information

Ronaldo is playing outside and shoots a ball of mass 2 kg horizontally with a speed of 8.0 m/s toward a green cart. The mass of the green cart is 15 kg and it rolls at a speed of 1.0 m/s along a horizontal path with no friction. The ball gets stuck in the card. What is the velocity of the cart after the ball strikes it? What are the initial and final kinetic energies of the system? Is the energy conserved in this collision process? What type of collision process is it?

A 80. kg hockey goalie is standing with his skates straight ahead, so there is no friction between his skates and the ice.  In Play A, he catches a 0.20 kg hockey puck moving at 40. m/sec.  In Play B, he catches a 8.0 kg medicine ball moving in the same direction at 1.0 m/sec.  In which case is the goalie pushed back faster?  Explain your reasoning, or show supporting work.

A father racing his son has 1/2 the kinetic energy of the son, who has 1/2 the mass of the father. The father speeds up by 1.1 m/s and then has the same kinetic energy as the son. What are the original speeds of (a) the father and (b) the son? (a) Number i Units (b) Number i Units

C10T.2 Two hockey pucks are initially at rest on a horizon- tal plane of frictionless ice. Puck A has twice the mass of puck B. Suppose puck until each puck has crossed a finish line 1 m away from its starting point. How do the puck's kinetic energies we apply the same constant force on each compare when each crosses the finish line? A. KA= 4KB В. КА — 2Кв C. KA= KB D. KB=2KA Е. К, — 4КА F. Some other relationship (specify) В = 4KA
