A 1 kg ball bounces off the ground as shown: 45° The ball's kinetic energy immediately beforehand is 50 J. The coefficient of restitution for the collision is e = 1/V2. The ball's linear momentum in the r direction is conserved through the collision 1. How fast is the ball going right after it bounces? 2. How much energy is lost in the collision? 3, Assuming that g = 10 m/s2, how high will the ball bounce?

A ball of mass m moving at 5 m/s at 0° bounces off an identical ball of mass m at rest. The first ball bounces off the second ball and moves away at a velocity of 2.5 m/s and an angle of -60°. If the second ball is moving at 4.36 m/s after the cos m bounce, what is its angle? SrM 0

2. Allison throws a tennis ball graphical analysis (Allotted Time 45 minutes) Allison throws a tennis ball at timet0 from a height above the ground equal to her own height. We assume that the positive horizontal direction is the positive r-direction, and the positive vertical direction is the positive y-direction. The ball has At times and t2, the ball bounces on the ground for the first, and second times respectively after being thrown. We assume that each bounce is instantaneous....

A ball is tossed straight upwards with an initial velocity of .30.00 metres per second from a height of 20,000 meters. Assume that the only force acting on the object is acceleration due to Earth's gravity. Write out the position and velocity functions. With what velocity does the object hit the ground? When the object hits the ground, it bounces back up with one-fourth the speed that it had when it hit the ground. Determine the height of the ball...

A ball is launched from the ground at an angle of 65∘ above the horizontal with a velocity of 22m/s. The ball hits the ground some distance away at a given speed, and bounces back up. When it does so the amplitude of both the x and y components of its velocity are half what they were. This repeats with the ball losing half of it’s speed on each bounce. a) Sketch the problem. [2 points b) Write the equation...

A 200 gram foam ball is propelled from ground level into the air with an initial velocity of 13 m/s at an angle of 37 degrees from horizontal (+x direction). Halfway through its flight, it strikes a giant yellow bird flying at 8 m/s in the -x direction. This causes the ball's velocity to be reduced by 20% but it continues flying thru the air. The bird loses one feather but is ok and continues flying at 7 m/s. After...

Allison throws a tennis ball at time t = 0 from a height h above the ground equal to her own height. We assume that the positive horizontal direction is the positive x-direction, and the positive vertical direction is the positive y-direction. The ball has a positive initial horizontal velocity vx, and no initial vertical velocity. At times t1 and t2, the ball bounces on the ground for the first, and second times respectively after being thrown. We assume that...

Let h = 25.5 m and vi = 11.8 m/s. Find the speed of the ball just before it hits the ground. vf = m/s Find the ball's mechanical energy at the release point. KEi + PEi = J Find the ball's mechanical energy just before it hits the ground. KEf + PEf = J Remarks Notice that the final speed does not depend on the initial release angle. Kinetic energy is not a vector. The initial kinetic energy of...

A ball is launched from the ground toward a tall wall of a building at initial speed v0 = 21 m/s at an angle of 42 degrees relative to the horizontal. The wall is at a distance of 29 m from the launch point. What is the magnitude of the ball's velocity vector as it hits the wall? Your answer should be in m/s, but enter only the numerical part in the answer box.
