The 1.5-kg collar C starts from rest at A and slides with negligible friction on the fixed rod in the vertical plane. Determine the velocity v with which the collar strikes end B when acted upon by the 14.4-N force, which is constant in direction. Neglect the small dimensions of the collar.
Answers: 1
is the height of the collar at position A, m is the mass of the collar C, g is the acceleration due to gravity, 
is the velocity of the collar at position B, and 
is the velocity of the collar at A
for g and 0 for
