A ball with an initial velocity of 11.5 m/s and mass 1.9 kg moves at an angle 65.5° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 65.5° above the horizontal, moving in the opposite direction with the same speed. See the figure. What was the magnitude of the impulse delivered by the wall, in kilogram meters per second?
A bat hits a ball of 0.145 kg. Initially, the ball travels to the right at 50 m/s, and after being hit it travels to the left at 30 degree respect to the horizontal and a speed of 65 m/s. Find the impulse applied to the ball The average force acting on the ball while it was in contact with the bat for 1.75 ms
The golfer hits the ball on a cliff as shown. The ball eventually lands on the 50-kg pad fastened to the 30° slope. If the coefficient of restitution between the ball and the pad is e-0.7, determine (a) the magnitude of the velocity of the ball when it rebounds from the pad (b) the angle measured from the slope of that velocity vector (c) the energyloss in J due to impact (d) the impulse exerted on the pad during impact...
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 particular horizontal turntable can be modeled as a uniform disk with a mass of 180 g and a radius of 30.0 cm that rotates without friction about a vertical axis passing through its center. The angular speed of the turntable is 2.00 rad/s. A ball of clay, with a mass of 40.0 g, is dropped from a height of 35.0 cm above the turntable. It hits the turntable at a distance of 15.0 cm from the middle, and sticks...
A ball of clay with a mass of 0.250 kg is traveling horizontally to the left with a speed of 12.0 m/s when it hits a rod that can rotate about an axis through its center. The rotational inertia of the rod is 0.800 kg middot m^2 and the rod has a length 1.20 m. If the ball sticks to the rod, what is the angular speed of the rod and ball after the collision?
A ball of soft clay with mass 1 kg falls from a height of 10 m starting at rest. When the clay hits the ground it flattens and comes to a stop. Which of the following is true? Gravity does work on the ball equal to 980 J, and all this energy is dissipated during the deformation of the ball on impact. Gravity does work on the ball equal to 98 J, and all of this energy is dissipated during...
