A machine in an ice factory exerts 3.06 ✕ 102 N of force to pull a large block of ice up a frictionless slope at constant speed. The force is applied parallel to the slope, and the weight of the block is 1.39 ✕ 104 N. What is the angle of the slope?

i have noo idea how to do this, please hellppppp A 15.6 kg block is dragged over a rough, hor- izontal surface by a constant force of 72.2 N acting at an angle of angle 34.8 above the horizontal. The block is displaced 24.6 m and the coefficient of kinetic friction is 0.234. ...

1.A 24 kg crate initially at rest on a horizon floor requires a 75 N horizontal force to set it in motion, once the crate is in motion, a horizontal force 53 N keeps the crate moving with a constant velocity. Find the coefficient of kinetic friction, between the floor and crate.

A 10 g bullet is fired into a 5 kg wooden block initially at rest on the floor. The bullet lodges in the block and the block slides 10 cm across the floor before coming to rest. If the coefficient of kinetic friction between the block and the floor is 0.5 what was the speed of...

General Physics
The 5 kg block in the figure slides down a frictionless curved ramp, starting from rest at a height of h = 3 m. The block then slides d = 12 m on a rough horizontal surface before coming to rest.What is the coefficient of friction between the block and the horizontal surface?

physics help please
The two blocks are connected by a light string that passes over a frictionless pulley with a negligible mass. The 3 kg block lies on a rough horizontal surface with a constant coefficient of kinetic friction 0:3. The hanging block has a mass of 8 kg. The system starts from ...
