Concept #1: Momentum & Impulse in 2D

Example #1: Momentum & Impulse in 2D

Practice: A 200-g ball going up diagonally hits a vertical wall with 10 m/s at an angle of 30° with the wall. It then rebounds with the same speed and same angle. What is the magnitude of the impulse delivered to the ball?

Additional Problems
A 3.00-kg steel ball strikes a wall with a speed of 10.0 m/s at an angle of θ = 60.0° with the surface. It bounces off with the same speed and angle as shown in the figure. 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?
Just before it is struck by a racket, a tennis ball weighing 0.560 N has a velocity of (20.0 m/s) i - (4.0 m/s) j. During the 3.00 ms that the racket and ball are in contact, the net force on the ball is constant and equal to (-380 N) i + (110 N) j. Find the:(a) x -component of the impulse of the net force applied to the ball(b) y-component of the impulse of the net force applied to the ball(c) x-component of the final velocity of the ball(d) y-component of the final velocity of the ball
A 0.155-kg baseball pitched horizontally at 35.5 m/s strikes a bat and is popped straight up to a height of 35.5 m. (a) If the contact time between bat and ball is 2.5 ms, calculate the magnitude of the average force between the ball and bat during contact. (b) Find the direction of the average force on the ball.
A 6 kg steel ball strikes a wall with a speed of 11.2 m/s at an angle of 50.5° with the normal to the wall. It bounces off with the same speed and angle, as shown in the figure. If the ball is in contact with the wall for 0.219 s, what is the magnitude of the average force exerted on the ball by the wall?1. 366.422. 239.5713. 170.7364. 390.365. 1456.096. 136.0937. 226.8328. 287.429. 335.95510. 714.377
