Big POPa. Group Members: Evan Hudspeth Stuart Haase Charlie Gang Dave Dickenson. Initial Step. Spin It!. τ= F·r F= m·a m= 0.032 slugs r= 0.167 ft The acceleration was found by constant acceleration equation: V2 2 =V1 2 +2ad d is the distance the ball travels which is 1.417 ft.
Perfectly inelastic collision
mball (Vball) + mcup(Vcup)= (mball+mcup)Vfinal
(0.0015slugs)(9.11 ft/s)+0=(0.0024 slugs) Vfinal
Vfinal= 5.69 ft/s
