Q. A 60.00kg crate is at rest on a level surface. If the coefficient of static friction, ms, between crate and the surface is 0.65, what horizontal force is necessary to move the crate? Draw FBD.

Q. Let the building is 50 m tall, the initial horizontal velocity is 9.0 m/s, and the initial vertical velocity is 12.0 m/s. select your coordinates such that the positive y-axis is upward, and the x-axis is to the right, and the origin is at the point where the ball is free.
