The 10kg crate below slides down a ramp with a rough surface, with μ k =0.25. Find the angle, θ , at which the crate will slide at a constant speed. θ
The 10kg crate below slides down a ramp with a rough surface, with μ k =0.25, at constant speed. Someone comes up to the crate and stops it. What will the crate do when the person walks away? 14°

Unformatted text preview: angle of 20° with the pole while is goes around. Draw a force diagram for the ball. While playing tetherball, you hit the 0.30kg ball such that the string makes a constant angle of 20° with the pole while is goes around. How fast is the ball moving? 1 meter A cargo jet travels in a vertical circle at 200m/s. A crate sits in the back of the jet. Draw a force diagram for the crate at θ . θ A cargo jet travels in a vertical circle at 200m/s. A crate sits in the back of the jet. What is the normal component of the force of the jet on the crate? θ A cargo jet travels in a vertical circle at 200m/s. A crate sits in the back of the jet. If μ s =0.3 and the crate starts slipping at θ =50°, what is the radius of the circular path? (Create an expression but do not solve.) θ...
