Step 1
First, we need to find the force of friction between the sled and the grass. The formula for the force of friction is: F_friction = μ * F_normal where μ is the coefficient of kinetic friction (0.30) and F_normal is the normal force, which is equal to the weight Show more…

A football player at practice pushes a 60 kg blocking sled across the field at a constant speed. The coefficient of kinetic friction between the grass and the sled is 0.40. How much force must he apply to the sled if he pushes straight horizontally at 30 degrees?

A 200kg football blocking sled rests on a football practice field. the coefficient of static friction between the sled and the ground is .73, while the coefficent of dynamic friction between the sled and the ground is .65. A) what magnitude of horizontal force below is the maximum force that a football players can push on the sled and have it not move? B) what will the sleds horizontal acceleration be if somebody was to push on the sled with a horizontal force of 2000N?
