A 50.0 g ball is shot in the horizontal direction, aimed directly at a wall. The initial speed of the ball is 13.0 m/s, whereas when the ball bounces back, it is moving at 12.0 m/s in the opposite direction. If the contact between the ball and the wall lasts t=0.250 s, what is the strength of the force the wall exerts on the ball? Give your answer in units of newtons, to three significant figures.

A golf ball is hit from the ground (elevation is zero) and takes off with a launch speed of 55 m/s and a launch angle of 25 degrees. The acceleration due to gravity g = 9.81 m/s2 downward (negative y direction). The wind resistance is proportional to velocity and is defined by constant k = 0.014 N / (m/s). The mass of the golf ball m = 46 grams. 1) Determine the horizontal x1(t) and vertical y1(t) positions as a function of time ignoring air / wind resistance in both the x and y directions. 2) Determine the horizontal x2(t) and vertical y2(t) positions as a function of time including air / wind resistance in both the x and y directions. 3) For the case ignoring wind / air resistance, calculate how long the ball is in the air (in seconds) and how far away the ball lands from where it was hit (in meters).
A 1.90 kg box is moving to the right with speed 9.00 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box.

Alex is asked to move two boxes of books in contact with each other and resting on a frictionless floor. He decides to move them at the same time by pushing on box A with a horizontal pushing force p =7.5N. Box A has a mass = 10.5 kg and box B has a mass 7.0 kg. The contact force between the two boxes is F and N denotes the normal force. A) What is the acceleration (in m/s to the 2nd) of the two boxes B) What is the force (in N) exerted on mb by ma? C) If Alex were to push from the other side on the 7.0 kg box, how would your answer to part (b) change?
