A 4.10-kg steel ball strikes a wall with a speed of 13.0 m/s at an angle of ? = 60.0° with the surface. It bounces off with the same speed and angle (see figure below). If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ball? (Assume right and up are the positive directions.) Fx =  N Fy =  N

A car of mass 1,907 kg collides with a wall. The initial speed of the car is 18.2 m/s. After collision, the car bounced in the opposite direction at a speed of 2.9 m/s. If the collision lasted for 172 ms, what was the average force in newtons exerted on the car by the wall? Express your answer in two decimal places with units of Newton.

A 4.10-kg steel ball strikes a wall with a speed of 11.0 m/s at an angle of ? = 60.0° with the surface. It bounces off with the same speed and angle (see figure below). If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ball? (Assume right and up are the positive directions.) Fx =   Fy =

A 59.5 kg man standing on a frictionless surface pushes two large boxes in opposite directions as shown. Initially everything is a rest. If the left box has mass 41.5 kg and final speed 3.25 m/s, and the right box has mass 27.0 kg and final speed 2.00 m/s, what is the final velocity (magnitude and direction) of the man? Let the positive direction be to the right.

A 340-g ball B is hanging from an inextensible cord attached to a support C . A 170-g ball A strikes B with a velocity v0 with a magnitude of 1.5 m/s at an angle of 60° with the vertical. Assuming perfectly elastic impact (e= 1) and no friction, determine the height h reached by ball B.

A 3.90-kg steel ball strikes a wall with a speed of 9.0 m/s at an angle of 0= 60.0° with the surface. It bounces off with the same speed and angle (see figure below). If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ball? (Assume right and up are the positive directions.) F₁ = N F₂ Submit Answer Ⓡ a delete

A 2.72-kg steel ball strikes a massive wall at 10.0 m/s at an angle of 0 = 60.0° with the plane of the wall. It bounces off the wall with the same speed and angle (see the figure below).

A baseball (m= 150 g) approaches a bat horizontally at a speed of 43.9 m/s (98.2 mi/h) and is hit straight back at a speed of 52.6 m/s (118 mi/h). If the ball is in contact with the bat for a time of 1.27 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction. Number i Units VO Vf

Treat the collision as elastic.  A moving billiard ball hits an identical (except for color) stationary ball.   After the collision, the orange ball always goes off in the positive x-direction.  The final speeds are v and V.  Calculate the angle θ that the green ball goes off in.  (θ should be positive.) V0 = the initial green body's speed = 6 m/s M = the mass of both balls = 6 kg φ = the incoming green ball's angle = 70o It's always a good idea to check your answer with the momentum-conservation and energy-conservation equations.
