Aracquet ball with mass m = 0.256 kg is moving toward the wall at v = 11.8 m/s and at an angle of θ = 29° with respect to the horizontal. the ball makes a perfectly elastic collision with the solid, frictionless wall and rebounds at the same angle with respect to the horizontal. the ball is in contact with the wall for t = 0.066 s.1)what is the magnitude of the initial momentum of the racquet ball? kg-m/s2) what is the magnitude of the change in momentum of the racquet ball? kg-m/s3) what is the magnitude of the average force the wall exerts on the racquet ball? n4) ballhitswall2 now the racquet ball is moving straight toward the wall at a velocity of vi = 11.8 m/s. the ball makes an inelastic collision with the solid wall and leaves the wall in the opposite direction at vf = -7.8 m/s. the ball exerts the same average force on the ball as before. what is the magnitude of the change in momentum of the racquet ball? kg-m/s5) what is the time the ball is in contact with the wall? s6). what is the change in kinetic energy of the racquet ball? j

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
