Julia  pass a basketball to her friend Luna by making a bounce pass.  Julia throws a 0.60 kg basketball toward the floor at a speed of 7 m/s and at an angle of 65 degrees with respect to the vertical.  If the ball rebounds with the same speed and angle towards Luna, calculate the impulse delivered to the ball by the floor.  Choose up and away from Julia as your positive direction.

Sven hits a baseball  (m = 0.15 kg).  He applies an average force of 51.0 N. The ball had an initial velocity of 32.5 m/s to the right and a final velocity of 44.0 m/s to the left as viewed by a fan in the stands. (a) What is the impulse delivered by Sven's bat to the baseball? (Assume to the right as viewed by the fan is positive. Indicate the direction with the sign of your answer.) kg · m/s(b) How long is his bat in contact with the ball? s

A ball of mass 0.160 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.870 m. What impulse was given to the ball by the floor? magnitude direction

In a softball game, a 0.2 kg ball crosses the plate at 10 m/s at an angle of 45° on its way down. The batter hits the ball toward center field, giving it a velocity of 45 m/s at 30° above the horizontal. a. Determine the impulse given to the ball. b. If the force on the ball increases linearly for 4 ms, holds constant for 20 ms, and then decreases to zero linearly in another 4 ms. i) What is the average force on the ball? ii) What is the peak force on the ball? 4

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 At = 0.471 ms, and the radar gun clocks the speed of the ball as Ub = 146 mph after it comes off the club. The golf ball has a mass of mb = 45.9 g. What is the magnitude of the impulse imparted to the ball by the club? magnitude of the impulse: 67.014 Incorrect What is the magnitude of the average force of contact between the club and the ball? magnitude of the average force of contact: 142280.25 Incorrect kg. m S N

Two rams are fighting and run straight at each other. Ram 1 has m1 = 115 kg and an initial velocity v1 = 9 m/s. Ram 2 has m2 = 127 kg and an initial velocity v2 = -7 m/s. When they collide, they lock horns.  What impulse did Ram 2 deliver to Ram 1?

A 130.0 g ball is moving horizontally to the west at 20.0 m/s when it is hit by a stick. The ball flies off to the 20.0° north of east at 45.0 m/s. What are the magnitude and direction of the impulse that the stick delivers to the ball? 4.90 Ns, 55.4° north of east 10.1 Ns, 76.1° north of east O 3.52 Ns, 34.6° north of east O 3.52 Ns, 55.4° north of east 8.34 Ns, 13.9° north of east O 4.90 Ns, 34.6° north of east 10.1 Ns, 13.9° north of east 8.34 Ns, 76.1° north of east

A 0.500-kg ball is dropped from rest at a point 1.10 m above the floor. The ball rebounds straight upward to a height of 0.480 m. Taking the negative direction to be downward, what is the impulse of the net force applied to the ball during the collision with the floor?

A rubber ball of mass 30.0 g is dropped from a height of 2.00 m onto a floor. The velocity of the ball is reversed by the collision with the floor, and the ball rebounds to a height of 1.50 m. What impulse was applied to the ball during the collision?

Force of a Baseball Swing. A baseball has mass 0.141 kg. If the velocity of a pitched ball has a magnitude of 46.0 m/sm/s and the batted ball's velocity is 58.0 m/sm/s in the opposite direction, find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat. If the ball remains in contact with the bat for 1.6 msms , find the magnitude of the average force applied by the bat.
