a. Starting from rest, a crate of mass m is pushed up a frictionless slope of angle
Question:
a. Starting from rest, a crate of mass m is pushed up a frictionless slope of angle θ by a horizontal force of magnitude F. Use work and energy to find an expression for the crate’s speed v when it is at height h above the bottom of the slope.
b. Doug uses a 25 N horizontal force to push a 5.0 kg crate up a 2.0-m-high, 20° frictionless slope. What is the speed of the crate at the top of the slope?

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
