A lady moves a suitcase of mass 22.3 kg with frictionless wheels across a horizontal floor by pulling on a cord attached to the suitcase making an angle of 0 = 46.4 degrees to the horizontal, as shown in the diagram. If the lady pulls the cord with a force of 15.1 N, what is the magnitude of the acceleration of the suitcase, in units of m/s2

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

During a car accident, a 125kg driver is moving at 31m/s and in 1.5s is brought to rest by an inflating air bag. what is the magnitude of the change in momentum to the driver

Four 5-gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. use the following specific heat capacity data to determine which block will increase its temperature the most.
