4. A block that has a mass of 750 kg is suspended by a rope from the end of a construction crane. The crane is moving the block upward with an acceleration of 2.5 m/s²

a) Draw the free-body diagram of this situation. Label all of the forces with the appropriate
symbol. Be sure that the lengths of your arrows accurately represent the magnitudes of the forces.

b) What is the weight (Fg) of the block? Show your work. Label the weight in part a with the
magnitude you calculated here.

c) What is the net force acting on the block? Show your work.

it is easily magnetized.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
