The Concept of Potential Energy
PHXI06:WORK ENERGY AND POWER

355623 A spring is kept compressed by a small cart of mass 150 \(g\). On releasing the cart, it moves with a speed of \(0.2\,m{s^{ - 1}}\). The potential energy of the spring is

1 \(6 \times 10^{-3} \mathrm{~J}\)
2 \(1 \times 10^{-4} J\)
3 \(4 \times 10^{-4} \mathrm{~J}\)
4 \(3 \times 10^{-3} \mathrm{~J}\)
PHXI06:WORK ENERGY AND POWER

355624 The rectangular blocks \(A\) and \(B\) of masses 2 \(kg\) and 2 \(kg\) respectively are connected by a spring of spring constant \(10.8\;N\;{m^{ - 1}}\) and are placed on a frictionless horizontal surface. The block \(A\) was given an initial velocity of \(0.15\;m\;{s^{ - 1}}\) in the direction shown in the figure. The maximum compression of the spring during the motion is
