In a croquet shot a pair of touching balls are hit sharply by the mallet in the direction of the dotted line which is 30° off the axis of the ball centres as shown in the figure below. At what angle e will ball A travel at after the strike assuming that the contact between the balls is perfectly elastic? OA 0° B. 30° ○ C.90° ○ D. 45° ○ E. 60° 30 0 8 Mallet Strike

A boy slips off a spherical ice mound of radius 7.  At what height above the ground does the boy lose contact with the ice?  Assume the ice is frictionless.

2. A cart of mass 300 g moving along a straight track hits a 500 g cart which had been sitting still. After the carts hit, the 300 g cart has a speed of 1.0 m/s back to where it came from, while the 500 g cart is moving forward at 3.0 m/s in the same direction as the 300 g cart had been going at the beginning. How fast was the 300 g cart going before it hit the 500 g cart?

A 26-gg rifle bullet traveling 240 m/sm/s embeds itself in a 3.2-kgkg pendulum hanging on a 2.9-mm-long string, which makes the pendulum swing upward in an arc.  a. Determine the vertical component of the pendulum's maximum displacement. Express your answer to two significant figures and include the appropriate units. b. Determine the horizontal component of the pendulum's maximum displacement. Express your answer to two significant figures and include the appropriate units.
