A heavy crate is attached to the wall by a light rope. Another rope hangs off the opposite edge of the box. If you slowly increase the force on the free rope by pulling on it in a horizontal direction, which rope will break? Ignore friction and the mass of the ropes.
A speedboat starts from rest and accelerates at +2.32 m/s2 for 6.78 s. At the end of this time, the boat continues for the additional 5.34 s with an acceleration of +0.677 m/s2. Following this, the boat accelerates at -0.686 m/s2 for 8.68 s.
The maximum tension that a 0.5m string can tolerate is 14N. A 2.5kg ball is attracted to the string being whirled in a vertical circle. What is the maximum speed the ball can have at the top of the circle.
As part of a safety investigation, two 1900 kg cars travelling at 19 m/s are crashed into different barriers. Determine the average forces exerted on (1) car that hits a line of water barrels and takes 1.7 s to stop, and (2) car that hits a concre..
