Question

Part A Calculate the nonconservative work, , done by water resistance on the rock, the gravitational potential energy of the system, , the kinetic energy of the rock, , and the total mechanical energy of the system, , when the depth of the rock below the water's surface is 0 . Express your answers using two significant figures separated by commas. Part B Calculate the nonconservative work, , done by water resistance on the rock, the gravitational potential energy of the system, , the kinetic energy of the rock, , and the total mechanical energy of the system, , when the depth of the rock below the water's surface is 0.50 . Express your answers using two significant figures separated by commas. Part C Calculate the nonconservative work, , done by water resistance on the rock, the gravitational potential energy of the system, , the kinetic energy of the rock, , and the total mechanical energy of the system, , when the depth of the rock below the water's surface is 1.0 . Express your answers using two significant figures separated by commas.

Explanation / Answer

The work non conservative work is 4.2 * 1.8 meters....and its postive U is mgh = 2.5 *1.8 * 9.8 Joules ...its negative KE of rock is found by taking into accout the bouyant force and the non - conservative work. mgh + NonConsr Work + WorkFrom buoyancey -KE = 0 Every thing is in the same direction except the KE. Solve for v sqrt(2*(mgh + NonConsr Work + WorkFrom buoyancey) /m) = v and it should be negative
