A 0.150 kg ball hits a wall with a velocity of (5.1m/s)I + (5.7m/s)j + (5.5m/s)k. it rebounds from the wall with a velocity of (2.8m/s)I + (3.6m/s)j -(3.9m/s)k. In unit-vector notation, what are (a) the change in the ball's momentum, (b) the impulse on the ball, and (c) the impulse on the wall?
A Ball Hits a Wall Elastically Part A A ball of mass m moving with velocity strikes a vertical wall as shown in (Figure 1). The angle between the ball's initial velocity vector and the wall is 0, as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is Δ, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning...
I'm not sure what I'm doing wrong... A pitcher throws a 0.200 kg ball so that its speed is 18.0 m/s and angle is 40.0° below the horizontal when a player bats the ball directly toward the pitcher with velocity 46.0 m/s at 30.0° above the horizontal. Assume ti to be along the line from the batter to the pitcher and +j to be the upward vertical direction. (Express your answers in vector form.) (a) Determine the impulse (in N...
During a collision with a wall, the velocity of a 0.200-kg ball changes from 20.0 m/s toward the wall to 12.0 m/s away from the wall. If the time the ball was in contact with the wall was 60.0 ms, what was the magnitude of the average force applied to the ball?
A 1-kg ball in the air has an initial velocity vo = [ -20 ] i + [ -20 ] j m/s. It falls for a total time of 1 s. Assume that positive x-values are to the right and positive y-values are upward. What is the initial momentum pi of the ball? -20 i + -20 j kg*m/s What is the impulse or change in momentum ∆p of the ball? 0 i + -10 j kg*m/s What is the final momentum pf of the ball?...
A ball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. If the ball hits the floor with a speed of 3.30 m/s and rebounds with a speed of 1.50 m/s, determine the following. (a) magnitude of the change in the ball's momentum in kg · m/s (Let up be in the positive direction.) (b) change in the magnitude of the ball's momentum in kg · m/s (Let negative values indicate a decrease...
