A 20.0-kg crate, starting from rest, is pulled across a floor with a constant horizontal force F. for the first 9.00 m the floor is frictionless, and for the next 12.0 m the coefficient of friction is 0.200. The final speed of the crate after being pulled these 21.0 m is 18.0 m/s. How much is the constant horizontal force F mentioned above?

Part C Review A 4.5 kg box slides down a 5.2-m -high frictionless hill starting from rest, across a 2.3-m -wide horizontal surface then hits a horizontal spring with spring constant 470 N/m How far is the spring compressed? Express your answer using two significant figures The other end of the spring is anchored against a wall The ground under the spring is frictionless, but the 2.3-m- long horizontal surface is rough. The coefficient of kinetic friction of the box...

1- How much work is done by the horizontal force Fp = 150N on the 18-kg block when the force pushes the block 5.0 m up along the 32° frictionless incline? (b) How much work is done by the gravitational force on the block during this displacement? (c) How much work is done by the normal force? (d) What is the speed of the block (assume that it is zero initially) after this displacement? [Hint: Work-energy involves net work done.]...

A large crate is at rest on a horizontal floor. The coefficient of static friction between the crate and the floor is 0.500. A force F⃗ is applied to the crate in a direction 30.0∘ above the horizontal. The minimum value of F required to get the crate to start sliding is 410 N. Part A What is the mass of the crate? Express your answer with the appropriate units.
