A 10-lb collar is attached to a spring and slides without friction along a fixed rod in a vertical plane. The spring has an undeformed length of 14 in. and a constant k = 4 lb/in. Knowing that the collar is released from rest in the position shown, determine the potential energy at position B due to the spring and gravity. Note the position of the datum (where y = 0).

Question

A 10-lb collar is attached to a spring and slides without friction along a fixed rod in a vertical plane. The spring has an undeformed length of 14 in. and a constant k = 4 lb/in. Knowing that the collar is released from rest in the position shown, determine the potential energy at position B due to the spring and gravity.

Note the position of the datum (where y = 0).

O a. (Ve) = 32.7 and (Vg) = -11.7 lb ft
O b. (Ve) = 0 and (Vg) = -11.7 lb ft
O c. (V₂)
11.7 and (Vg) = 32.7 lb ft
O d. (Ve) = 32.7 and (Vg) = 11.7 lb ft
