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...

A 13.28 kg skater moving initially to the right at 9.51 m/s on rough horizontal ice comes to rest uniformly (constant acceleration) in 2.12 s due to friction from the ice. What is the acceleration of the skater due to friction?
A 102.08 kg skater moving initially to the right at 5.3 m/s on rough horizontal ice comes to rest uniformly (constant acceleration) in 5.1 s due to friction from the ice. What is the acceleration of the skater due to friction?
A 92.71 kg skater moving initially to the right at 0.39 m/s on rough horizontal ice comes to rest uniformly (constant acceleration) in 5.85 s due to friction from the ice. What force does friction exert on the skater?
A young ice skater with mass 35.0 kg has fallen and is sliding on the frictionless ice of a skating rink with a speed of 20.0 m/s. a. What is the magnitude of her linear momentum when she has this speed? Express your answer with the appropriate units. b. What is her kinetic energy? Express your answer with the appropriate units. c. What constant net horizontal force must be applied to the skater to bring her to rest in 6.00 s?...
Darcy and Wilhelmina now tackle a homework problem. An ice skater of mass m = 60 kg coasts at a speed of v = 0.71 m/s past a pole. At the distance of closest approach, her center of mass is r1= 0.37 m from the pole. At that point she grabs hold of the pole. (A) What is the skater's angular speed when she first grabs the pole? _______ rad/s (B) What is the skater's angular speed after she now pulls her center of...
A 54.9 kg ice skater is moving at 4.07 m/s when she grabs the loose end of a rope, the opposite end of which is tied to a pole. She then moves in a circle of radius 0.804 m around the pole. (a) Determine the force exerted by the horizontal rope on her arms. _________N (b) What is the ratio of this force to her weight? __________(force from part a / her weight)
Question 6) A 50.0 kg skater arrives at the bottom of a vertical circular track at 32.0 m/s. The radius of the track is 15.0 (m). Friction is negligible. Ignore the size of the skater so the radius of her motion is the hane as the 15.0fm] radius of the track. Point C is at the top of the track. The track goes a little bit farther than point C but we don't need to figure out what happens after...
