A6.25-kg bowling ball moving at 8.95 m/s collides with a 0.95-kg bowling pin, which is scattered at an angle of θ = 27.5° from the initial direction of the bowling ball, with a speed of 11.6 m/s. show answer no attempt 50% part (a) calculate the direction, in degrees, of the final velocity of the bowling ball. this angle should be measured in the same way that θ is.

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
