A ball traveling with an initial momentum of 0.9 kg⋅m/s bounces
off a wall in the opposite direction with a momentum of -0.5
kg⋅m/s. What impulse vector was needed to do this?
(Remember: One dimensional vectors use + and - signs for
direction!)

A ball of mass 2 kg is traveling towards you at 15 m/s. You are at rest and have a mass of 75 kg. a. Assuming you catch the ball, what is your final velocity? b. Assuming the ball bounces off you and travels in the opposite direction with a velocity of 12 m/s, what is your velocity? Please use Conservation of Momentum Equations.
A ball with an initial velocity of 11.5 m/s and mass 1.9 kg moves at an angle 65.5° above the horizontal.
A ball with an initial velocity of 11.5 m/s and mass 1.9 kg moves at an angle 65.5° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 65.5° above the horizontal, moving in the opposite direction with the same speed. See the figure. What was the magnitude of the impulse delivered by the wall, in kilogram meters per second?
