an ice skater sits at rest
(4 pts) An ice skater sits at rest in the middle of a frictionless ice rink. She takes off both of her skates with a total mass of 2 kg and throws them away from her with a velocity of 10 mis. The mass of the ice skater without the skates on is 50 kg. If the wall is 1 0 m away, how long will it take her to reach the wall? a)...

A 65-kg ice skater stands facing a wall with his arms bent and then pushes away from the wall by straightening his arms. At the instant at which his fingers lose contact with the wall, his center of mass has moved 0.50 What is the average force exerted by the wall on him? What is the work done by the wall on him? What is the change in the kinetic energy of his center of mass? Express you answers in...

Three ice skaters meet at the center of a rink and each stand at rest facing the center, within arm’s reach of the other two. On a signal, each skater pushes himself away from the other two across the frictionless ice. After the push, skater A with mass mA = 80.0 kg moves in the negative y-direction at 3.50 m/s and skater B with mass mB = 75.0 kg moves in the negative x-direction at 4.00 m/s. Find the x-...

During a pair ice skating, a 60-kg female ice skater leaps into the air and is caught by her 70-kg partner who was stationary. a. Assuming negligible friction on ice what is the velocity of the pair if the horizontal velocity of the female skater right before she was caught in the air was 5 m/s? b. What is the total KE before she was caught? What is the total KE after she was caught? c. Knowing that the skaters...

1) A 48.5-kg skater is standing at rest in front of a wall. By
pushing against the wall she propels herself backward with a
velocity of -1.46 m/s. Her hands are in contact with the wall for
1.00 s. Ignore friction and wind resistance. Find the average force
she exerts on the wall (which has the same magnitude, but opposite
direction, as the force that the wall applies to her). Note that
this force has direction, which you should indicate...

Please provide me a step by step analysis of how i would solve this problem? An ice skater is holding out a 18 kg mass in her hand and is spinning with a linear velocity of 4.0 m/s with her arms extended 0.80 meters long in relation to the center of her body. If she pulls her arm in, still holding the 18 kg mass, so that she extends her arms to 0.20 meters, what will the Velocity of the...

A 40 kg sled on frictionless ice is at rest next to you. You are standing on the ground. You push on it with a force of 10 N for 3 seconds. The sled moves away. You remain stationary. a. How much total impulse was applied to the sled? (in N•s) b. What is the final velocity of the sled? c. How much impulse did the sled apply to you? d. What is your final velocity?
