Two people pull a block on a rough horizontal surface. One suggests to use a rope that is inclined at angle 70° and another suggests to use a rope at angle 20°. If they pull for the same horizontal distance with the same strength of force, which person does more work? At the end of the same distance pulled, which block is moving faster? Instead, the surface over which the blocks move is now frictionless. How does this change your answers to the questions above?

I drive a Nissan Leaf to work. With the e-pedal on, the motor recovers energy through braking very aggressively. I need about 7 KW-hour to come to school if I use mostly the freeways. That’s about 5 KW-hour if I take mostly local streets. From the energy perspective, can you offer an explanation to explain this difference?
A 10 kg barbell is rolling down a hill. There is no friction or air resistance acting on it, only the force of gravity. If it starts out moving 2 ms1, and ends up moving 7 ms1, then how much work does gravity do on it?

Q14. A 2 kg mass is projected down a rough circular track (R = 2m) as shown. The speed of the mass at point A is 4 m/s, and at point B, it is 6 m/s. How much work is done on the mass between A and B by the force of friction?
Person A and Person B are both using the same amount of work to lift something. Person A takes half as much time to do it. Using the formula for power, explain which person has the most Power and why.
