At the end of a ride at a winter-theme amusement park, a sleigh with mass 250 kg (including two passengers) slides without friction along a horizontal, snow-covered surface. the sleigh hits one end of a light horizontal spring that obeys hooke’s law and has its other end attached to a wall. the sleigh latches onto the end of the spring and subsequently moves back and forth in shm on the end of the spring until a braking mechanism is engaged, which brings the sleigh to rest. the frequency of the shm is 0.225 hz, and the amplitude is 0.950 m. (a) what was the speed of the sleigh just before it hit the end of the spring? (b) what is the maximum magnitude of the sleigh’s acceleration during its shm?

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.
