In a game of curling, a collision occurs between two stones of equal mass. The object stone is initially at rest. After the collision, the stone that is thrown hasa speed of 0.56m/s in some direction, represented by q. The object stone acquires a velocity vf2= 0.42m/s at an angle of f= 30.0o from the original direction of motion of the thrown stone. Determine the initial velocity of the thrown stone.

A bullet of mass m = 8.00 g is fired into a block of mass M = 220 g 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 = 1.60 m from the bottom of the table. Determine the initial speed of the bullet. __ m/s
Kyle, a 95.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 0.538 meters off the ground. He hits the ground 0.0333 metersaway from where he leapt. If the ball was moving horizontally when it was caught, how fast was the ball traveling? ball's speed: ? m/s
A truck (M = 2500kg) collides with a car (m = 1000kg) at a 4-way intersection. Fortunately nobody gets hurt.
