A tennis ball of mass 57.0 g is held just above a basketball of mass 597 g. With their centers vertically aligned, both balls are released from rest at the same time, to fall through a distance of 1.30 m, as shown in the figure below.(a) Find the magnitude of the downward velocity with which the basketball reaches the ground.m/s(b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball while the tennis ball is still moving down. Next, the two balls meet in an elastic collision. To what height does the tennis ball rebound?

A woodblock of mass Mw = 200 g is projected from the ground at a speed v0 = 35 m/s and at an angle, θ0 = 50º. When at height h = 24 m the woodblock was hit by a bullet of mass Mb = 25 g which was moving at vb = 220 m/s and at an angle θb = 70º. After the collision, the bullet embedded itself in the block and move together and land at point A on the ground. Then they move on the ground that has a coefficient of kinetic friction µk = 0.5 and starts to compress a horizontal spring at point B. The distance between point A and B is 18 m and the spring constant k = 3×10^2 N/m. The right end of the spring is fixed, and all motions are confined in x-y plane.

You have just planted a sturdy 2-m-tall palm tree in your front lawn for your mother’s birthday. Your brother kicks a 500g ball, which hits the top of the tree at a speed of 5 m/s and stays in contact with it for 10 ms. The ball falls to the ground near the base of the tree and the recoil of the tree is minimal. (a) What is the force on the tree? (b) The length of the sturdy section of the root is only 20 cm. Furthermore, the soil around the roots is loose and we can assume that an effective force is applied at the tip of the 20 cm length. What is the effective force exerted by the end of the tip of the root to keep the tree from toppling? Assume the tree will be uprooted rather than bend. (c) What could you have done to ensure that the tree does not uproot easily?

A bullet of mass m = 8.00 g is fired into a block of mass M = 240 a that is initially at rest at the edge of a table of height h = 1.00 m (see figure below). The bullet remains in the block, and after the impact the block lands d = 1.50 m from the bottom of the table. Determine the initial speed of the bullet. Use the given information to find the velocity of the block after collision with the bullet and then use conservation of momentum to find the initial speed of the bullet. m/s Need Help?
