A 0.12-kg ball is moving at 6 m/s when it is hit by a bat, causing it to reverse direction and have a speed of 14 m/s. What is the magnitude of the change in the momentum of the ball? 0.39 kg middot m/s 0.42 kg middot m/s 1.3 kg middot m/s 2.4 kg middot m/s Alex throws a 0.15-kg rubber ball down onto the floor. The ball's speed just before impact is 6.5 m/s, and just after is 3.5...
Billiard ball 1 is moving in the positive direction at a speed of 3.00 m/s, and it strikes billiard ball 2 (at rest). After the collision, billiard ball 1 is moving at 0.50 m/s at an angle of 50 counter clockwise from positive-x. What is the velocity vector of billiard ball 2 if the balls are of equal mass (300 grams )?
A soccer ball of mass 0.50 kg is rolling with velocity 0, 0, 1.8 m/s, when you kick it. Your kick delivers an impulse of magnitude 1.2 N · s in the −x direction. The net force on the rolling ball, due to the air and the grass, is 0.22 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s...
Suppose the mass of the ball is 60 g and it is spinning at 40 rad/s at a distance of 1.5 m from the center of rotation. The force is 1800 N and it’s applied for 2 ms. Your goal is to find the final angular speed of the tennis ball. i. What is the initial angular momentum of the tennis ball? Hint: 40 rad/s is the angular speed (?), NOT the linear speed (?). If the angular speed is...
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...
A ball of mass m moving with velocity v_i_vec strikes a vertical
wall. The angle between the ball's initial velocity vector and the
wall is theta_i 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 Deltat, and this collision is completely
elastic. Friction is negligible, so the ball does not start
spinning. In this idealized collision, the force exerted on the
ball by the...
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 3.12 m/s, rebounds with a speed of 1.89 m/s, and is in contact with the floor for 1.20 ms, determine the following. (a) magnitude of the change in the ball's momentum (Let up be in the positive ĵ direction.) kg · m/s (b) change in the magnitude of the ball's momentum (Let...
A 5 kg cart moving at a velocity 2 m/s in the +x-direction collides completely inelastically (i.e. they stick) with a second cart of mass 1.5 kg which is initially moving at a velocity of 10 m/s in the +y-direction. What is the total initial kinetic energy? J. What is the total x-component of momentum just before the collision? Kg m/s. What is the total y-component of momentum just before the collision? Kg m/s. What is the total x-component of momentum just after...
A billiard ball of mass = 300.0 g moving with an initial speed of 1.80 m/s strikes a second ball of mass mg 400.0 g initially at rest, As a result of the collision, the first ball is deflected off at an angle of 25.0 0 with a speed of 1.00 m/s. Do not assume this is a perfect collision, (a) Taking the x-axis to be the original direction of the motion of ball A, write down the equations of...
