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?
if any inquires please comment and if you satisfied please like.

Question 4 10 points Save Answer A skater is moving with an initial speed of 2.8 m/s on rough horizontal ice. He comes to rest uniformly after moving 4.6 m due to friction from the ice. What is the magnitude of friction force exerted on the skater if the mass of the skater is 72 kg? 7.9N 57N 46.7 N 61.4 N
On an essentially frictionless, horizontal ice rink, a skater moving at 6.0 m/s encounters a rough patch that reduces her speed by 46 % due to a friction force that is 26 % of her weight. Use the work-energy theorem to find the length of this rough patch.

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.
A 90 kg ice skater moving at 11.0 m/s on the ice encounters a region of rough up ice with a coefficient of kinetic friction 0.500. How far along the rough ice doe she go before stopping?
A speed skater moving across frictionless ice at 8.5 m/s hits a 5.9 m -wide patch of rough ice. She slows steadily, then continues on at 5.5 m/s What is her acceleration on the rough ice?
A 90 kgkg ice skater moving at 10.0 m/sm/s on the ice encounters a region of roughed up ice with a coefficient of kinetic friction of 0.360. How far along the rough ice does she go before stopping?
5))A 40 kg ice skater is gliding along the ice, heading due north at 4.4 m/s. The ice has a small coefficient of static friction, to prevent the skater from slipping sideways, but µk = 0. Suddenly, a wind from the northeast exerts a force of 4.0 N on the skater. (a) Use work and energy to find the skater's speed after gliding 90 m in this wind. m/s (b) What is the minimum value of µs that allows her...
