A 28.5 g bullet strikes a 0.520 kg block attached to a fixed horizontal spring whose spring stiffness constant is 7730N/m . The block is set into vibration with an amplitude of 35.0 cm.
What was the speed of the bullet before impact if the bullet and block move together after impact?
If the elastic limit of steel is 5.0*10^8 Pa. determine the minimum diameter a steel wire can have if it is to support a 62 kg circus performer without its elastic limit being exceeded.
Calculate the increase in internal kinetic energy (that is, for the ship and the shell). This energy is less than the energy released by the gun powder-significant heat transfer occurs
Two teams of nine members each engage in a tug of war. The first team's members have average masses of 65 kg and exert average forces of 1350 N horizontally. What is the acceleration of the two teams
