If a rocket with a mass of $700 k g$ $700 kg$ vertically accelerates at a rate of $\frac{3}{2} \frac{m}{s^{2}}$ $3/2 m/s^2$ , how much power will the rocket have to exert to maintain its acceleration at 4 seconds?
A spring with a constant of $4 \frac{k g}{s^{2}}$ $4 (kg)/(s^2)$ is lying on the ground with one end attached to a wall. An object with a mass of $4 k g$ $4 kg$ and speed of $8 \frac{m}{s}$ $8 m/s$ collides with and compresses the spring until it stops moving. How much will the spring compress?
