A bowling ball is rolled up an incline as shown in Figure P9.30. If
the ball has a speed of 13 m/s at the base of the incline, to what
height h on the incline will the center mass travel?
Homework Answers
Kinetic energy, KE = 0.5 mv^2 + 0.5 x (2/5) mR^2 (v/R)^2
KE = (7/10) mv^2
Using law of conservation of energy,
(7/10) mv^2 = mgh
Height, h = 7 v^2/10 g
h = (7 x 13^2)/(10 x 9.8) = 12.07 m

A bowling ball (mass:6.5 kg) is thrown down a bowling alley with a speed of 8 m/s. where it has an off center collision with a bowling pin (mass: 1.5 kg). After the collision, the bowling ball moves off to the right of the original path of motion with a reduced speed of 6.2 m/s at an angle of 11.3 degrees as shown, while the bowling pin is deflected to an angle of 32.3 degrees to the left of the...
