You are out playing golf one day with your friends. And you decide to use your 60° wedge to play a shot. The start of the green is right at 110 meters away and the back is at 135 meters. Your club has a mass of .33 kg and the golf ball has a mass of 40 grams or .04 kg. You swing the golf club with a speed of 32 m/s.

Part 1. Say that we treat this as an elastic head on collision with the golf ball being stationary. What is the Velocity of the golf ball and golf club after impact? Give your answers to 3 significant digits.

Club: m/s

Ball: m/s

Part 2. What is the Impulse you applied to this golf ball? Give your answer to 4 significant digits.

kg*m/s

Part 3. If the ball was in contact with the head of the club for, Δt = .0025s, how much Force did you apply to the golf ball? Give your answer to 4 significant digits.

N

Part 4. If the ground is perfectly flat and you assume the ball launched with exactly a 60° angle from the ground, determine the max Height of the ball. (Neglect Air Resistance) Give your answer to 4 significant digits.

m

Part 5. How long did it take to reach this height? How long does the whole flight take? Give your answer to 3 significant digits.

Time to Height: s

Time of Flight: s

Part 6. Will your ball land on the green? (Neglect Air Resistance)

(yes or no only)

After your ball lands assume that the ball keeps half of the x-component of velocity it had in flight. And for simplicity let us say that because of the perfect backspin the ball slides along the grass surface. The coefficient of friction between the ball and the grass is .65.

Part 7. How much time does it take to come to a stop? Give your answer to 4 significant digits.

s

Part 8. How far does the ball slide before coming to a stop? Give your answer to 4 significant digits.

m

Two friends are playing golf. The first friend hits a golf ball on level ground with an initial speed of 43.5 m/s at an angle of 32.0° above the horizontal . (a) Assuming that the ball lands at the same height from which it was hit, how far away from the golfer, in meters, does it land? Ignore air resistance. (b) The second friend hits his golf ball with the same initial speed as the first, but the initial velocity...

Proposition. You and your friends are learning to play hockey, and you decide to use physics to get better by analyzing your movements. You are skating directly towards your friend at (5.98, 0) M/S who is also skating directly towards you to get the puck at a constant velocity of (-2.7, 0) M/S, and both of you reach the puck at the same time, so you collide and stick together. At the same time your hockey helmet with a mass...

For lunch, you and your friends decide to stop at the nearest deli and have a sandwich made fresh for you with 0.103 kg of turkey. The slices of turkey are weighed on a plate of mass 0.430 kg and placed atop a vertical spring of negligible mass, with a force constant of k = 170 N/m. The slices of turkey are dropped on the plate all at the same time from a height of 0.310 m. They make a...
