A 46 kg skater is standing still in front of a wall. By pushing against the wall she propels herself backward with a velocity of 1.2 m/s. Her hands are in contact with the wall for 0.80s. What is the MAGNITUDE of the resulting momentum of the skater after she starts moving?

A professional golfer is examining a video of a practice swing. The high‑speed footage shows that his club is in contact with the ball (which was initially at rest on the tee) for only Δ?=0.771 ms, and the radar gun clocks the speed of the ball as ?b=176 mph after it comes off the club. The golf ball has a mass of ?b=45.9 g. a. What is the magnitude of the impulse imparted to the ball by the club? b. What is the magnitude of the average force of contact between the club and the ball?

Two students are playing paddle ball with a 5 kg spongy ball. If the ball is thrown at the batter with a speed of 5 m/s and bounces off with a speed of 10 m/s. What is the magnitude of the impulse imparted on the ball by the bat?

A 20.0-kg object has an eastward momentum of 120 kg m/s. The object encounters a westward impulse of 40 N s. What is the magnitude of the final momentum of the object?

A soccer ball with a mass of 0.45 kg has a velocity of 2.0 m/s to the east. It experiences a sudden kick lasting 0.2 s, causing it to change both its speed and direction. Immediately after the kick, the ball has a velocity of 3.8 m/s to the north. What is the magnitude (in kg m/s) of the impulse that acted on the ball?

An object feels a force for 0.85 s. If you know the impulse on the object is 75 Ns, what was the average force applied to the object?
