A dump truck, with a mass of 2030 kg, moves at a constant speed 2.23 m/s along a horizontal track. The truck then passes under a loading container and, as it does so, rocks fall vertically into it for 3.21 s at the rate of 497 kg/s. What is the truck's speed after the loading is completed? Ignore rolling friction (as unrealistic as that may be).
Consider a damped oscillator with m=0.2 kg, b= 4 N-m^-1 sec and k= 80N/m. Suppose that this oscillator is driven by a force F=Fo cos wt, What is the mean power input
The circular top of a can of soda has a radius of 0.029m. The pull-tab has an area of 4.13 10-4m2. The absolute pressure of the carbon dioxide in the can is 1.4 x10^5Pa. Find out the force that this gas generates.
