7. - Moose the astronaut with a backpack have a mass 150 kg. He is on a spacewalk and is stranded 10 m away from the space station hatch. He removes and throws his 25 kg pack away from the space station with 500 N of force for 0.50 s. How long will it take Moose to reach the hatch? " -Midge has a mass of 50 kg and an initial velocity of 5.0 m/'s [N]. She grabs onto a shopping cart at rest of mass 20 kg in a manner that is perfectly inelastic. Determine the velocity of Midge and the cart after the she grabs onto it. - Sabrina the teenage witch animates a tennis ball of mass of 60 g to fly west at 108 km/h. It collided perfectly elastically with the back of Dilton's head. Dilton has a mass of 60 kg and an initial velocity of 3.0 m's [W]. Determine the final velocities of the tennis ball and Dilton. Perhaps the genius Dilton shouldn't say he is a supporter of the Salem witch trials in front of Sabrina. --9 p - Chuck shoots a cue ball at 20 m/'s, which then strikes the eight ball directly. The eight ball has twice the mass and the collision is perfectly elastic. Determine the final velocities of the cue ball and eight ball. G-Mr. Weatherbee has a mass of 100 kg and an initial velocity of 3.41 m/'s [E]. A 1.0 g superfly flying at west at Mach 10 accidentally collides with him, slowing him down to 3.40659 m's. Find the new velocity of the superfly and determine the if the collision was relatively elastic or inelastic by checking the energy lost in the collision which generates heat, sound, vibrations and light
