(Part 2 out of 2)Answer in 30 min and i'll choose best answer. No Need to show work just correct answer.

of magnitude F applied at an angle of 58.8degree with the horizontal. The acceleration of gravity is 9.8 m/s2. If the coefficient of kinetic friction between the block and wall is 0.409, find the work done by F. Answer in units of J 010(part 2 of 4) 10.0 points Find the work done by the force of gravity. Answer in units of J 011(part 3 of 4) 10.0 points Find the work done by the normal force between the block and the wall. Answer in units of J 012(part 4 of 4) 10.0 points By how much does the gravitational potential energy increase during this motion? Answer in units of J 013 10.0 points A 5.6 kg bowling ball is lifted 1.5 m into a storage rack. The acceleration of gravity is 9.8 m/s2. Calculate the increase in the ball's potential energy. Answer in units of J 014 10.0 points Tim, with mass 65.7 kg, climbs a gymnasium rope a distance of 2.3 m. The acceleration of gravity is 9.8 m/s2. How much potential energy does Tim gain? Answer in units of J

Explanation / Answer

let h is the displacement
normal force,N = F*cos(58.8)

2)frictional force, f = mue*N

workdone by friction = -mue*N*h

3) workdone by gracity = -m*g*h

4) increase in potential energy = m*g*h

13)

delta PE = m*g*h = 82.32 J

14)


delta pE = m*g*h = 1480.878 J
