9 Questions

1. Find the energy equation for the system shown in the figure. “m” is the mass of the block moving at a velocity “v”, “k” is the spring constant, “q” is the coefficient of friction of the floor and let “d” be the compression in the spring.
2. The following graph represents the parabolic plots of the potential energy V and kinetic energy K of a block attached to a spring obeying Hooke’s law.
3. The potential energy possessed by a spring is also known as _____
4. An object is travelling at a velocity of 10 m/s. It has a mass of 2 kg. It impacts a spring of spring constant “k” as shown in the figure. What is the compression of the spring?
5. Find the energy equation for the system shown in the figure. “m” is the mass of the block moving at a velocity “v”, “k” is the spring constant, “q” is the coefficient of friction of the floor and let “d” be the compression in the spring.
6. Assume a spring extend by 'd' due to some load. Let 'F' be the spring force and 'k' the spring constant. Then, the potential energy stored is _____
7. The elastic potential energy varies linearly with displacement.
8. A spring of length 1m has two cars connected to both of its ends. The two cars move towards eachother such that the spring is compressed to 0.5m. If the spring constant is 500 N/m, what is the elastic potential energy stored?
9. The following graph represents the parabolic plots of the potential energy V and kinetic energy K of a block attached to a spring obeying Hooke’s law.
