A 1.80 m tall man lifts a 2.00 kilogram book from the ground therefore it is 2.40 meter above the ground.
Find the potential energy of the book relative to the ground?
Find the potential energy of the book relative to the top of the man's head?
Describe how is the work done by the man related to the answers in parts A and B?
Two forces F1 and F2 are acting on a mass M=6.0 kg. The force F1 = 5.0i + 7.0j + 2.0k, in N. The acceleration of the mass is given by a = 2.0i + 7.0j + 5.0k, in m/s2. Calculate the magnitude of F2.
