A Klingon K'VortEnterprisea: If it took the Enterpriseb: A Ferengi D'KoraEnterpriseEnterprise
-class starship has a mass of approximately kg. The -D locks on its tractor beam and accelerates to m/s, towing the Klingon ship behind it.

about 5 seconds to reach that speed, how much force did it exert on the Klingon ship?

-class marauder appears and locks its tractor beam on the Klingon ship. It tries to tow it at m/s at a 90º to the right of the , as seen from above. What is the net velocity of the Klingon ship? (Hint: Assume the is traveling due north).

A candlepin bowling ball has a diameter of 11 cm and a mass of 1.1 kg. The lane is 18 m long. A good candlepin bowler can release the ball in about 2/3 of a second and the ball will be moving at about 13.41 m/s when it leaves their hand. The pins, of course, start at rest and each of them has a mass of 1.1 kg.

a: Assuming the friction is negligible for now, how long will it take for the ball to reach the pins?

b: Now assume there is enough static fiction to allow the ball to roll. What is the ball's angular velocity?

c: What is the kinetic energy of the ball? (Hint: the moment of inertia for a solid sphere is ).

d: Let's assume that the first 12 m of the lane were reasonably well oiled and have a coefficient of friction of .0700. The last 6 m are dry and have a coefficient of friction of .1808. How fast is the ball moving when it hits the first pin?

e: Assuming the ball hits the first pin head on in a perfectly elastic collision (the bowler is REALLY good), how fast will each of them be traveling after the collision?
