Question

A constant force F is applied on a spring-block system (Figure 5.137). The mass of the block is m and the spring constant is k . The block is on a smooth surface, and the spring is initially unstretched. Choose the correct alternative(s):

TestHub · Accepted Answer

The equilibrium shifts to x = F / k and the block oscillates about it with amplitude F / k (not F /2 k ) and T = 2 π m / k ​ . Work-energy: 2 1 ​ m v 2 = F x − 2 1 ​ k x 2 .
