1. An individual carrying a heavy wooden crate holds the crate against a vertical wall to take a break. If the 50 kg crate is pressed flush against the wall, what horizontal force must the individual apply to the crate to keep it from sliding down if the coefficient of friction is .15? If the wall is frictionless, can the individual still hold it against the wall with only a horizontal force? Why or why not? F 2. A football is kicked with an initial velocity of 20 m/s at an angle of 45 degrees. If the field goal is attempted from 35 meters away from the goal post (3m tall) does the football clear the post? (Find the height of the football at 35 meters). Also find the total horizontal distance the ball traveled. 3. How much force would it take to pull a 50 kg crate at constant velocity up a 10 degree incline with a coefficient of friction of .2
