Q. A package of mass 5 kg sits at the equator of an airless asteroid of mass 7.0 1020 kg and radius 4.5 105 m. We want to launch the package in such a way that it will never come back, and when it is very far from the asteroid it will be traveling with speed 202 m/s. We have a large and powerful spring whose stiffness is 1.3 105 N/m. How much must we compress the spring?
Q. A 380-N, uniform, 1.50-m bar is suspended horizontally by two vertical cables at each end. A small object of weight 520 N is placed distance 0.500 m from the cable A. What is the tension in cable A?
A simple harmonic oscillator consists of a block of mass 4.kg attached to a spring of spring constant 153 N/m. When t = 2 s, the position and velocity of the block are x = +0.129 m and v = +3.415 m/s.

A tuning fork vibrating at 666 Hz falls from rest and accelerates at 9.8 m/s 2. How far below point of release is the tuning fork when waves of frequency 626.4 Hz reach the release point? The speed of sound in air is 339 m/s.
A uniform plank of length 5.8m and weight 229N rests horizontally on two supports, with 1.10 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 450N walk on the overhanging part of the plank be..
Throughout a nuclear reactor accident, 570 m3 of water at 20o C is pumped into the reactor core which is producing heat at the rate of 250 MW. If the water is allowed to boil at normal atmospheric pressure how long would it take to boil away all this..
Megan's mass is 27 kg. She climbs the 4.8 m ladder of a slide and reaches a velocity of 3.6 m/s at the bottom of the slide. How much work was completed by friction on Megan? Imagine that air resistance is negligible.
