A 55 kg ice skater is at rest on a flat skating rink
Homework Answers
Kinetic mu = 175/(55*9.8)
Must be pretty rough ice. Get out the Zambomi.

A 55kg ice skater is at rest on a flat skating rink. A 198N horizontal force is needed to set the skater in motion. However, after the skater is in motion, ahorizontal force of 175N keeps the skater moving at a constant velocity. Find the coefficients of static and kinetic friction between the skates and the ice.

On an essentially frictionless horizontal ice-skating rink, a skater moving at 2.8 m/s encounters a rough patch that reduces her speed by 47 % to a friction force that is 22 % of her weight. Use the work-energy principle to find the length of the rough patch.

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 dockworker loading crates on a ship finds that a 25-kg crate, intially at rest on a horizontal surface, requires a 72-N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 50 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor. static friction kinetic friction

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?...

A dockworker loading crates on a ship finds that a 20-kg crate, initially at rest on a horizontal surface, requires a 73-N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 51 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor.
