A student measures the mass of a lead weight. She then applies a force of known magnitude in pushing the weight over a smooth surface. She measures the acceleration of the weight when acted on by the force. Which would be the BEST hypothesis for this investigation?

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
