HELP PLZ 1) A person wants to move a table from one side of the room to the other. The room is 15 meters across. If that person supplies a constant force of 500 N while pushing the table, how much energy will it take them to move it?

2)A person pushed a shopping cart down an aisle at the grocery store. The entire time that person supplied a constant force of 10 N on the cart. That person did 200 J of work pushing it from one end of the aisle to the other. How long was the aisle?

3) A car is driving down the road. What type of energy is stored in the motion of the car?

4) A person has a mass of 85 kg and is in a building 75 meters high. What is the person’s gravitational potential energy? (g = 10 m/s2)

5) A picture with a mass of 3 kg is sitting on a shelf. Its gravitational potential energy is 60 J. How is high is the shelf?

6) An astronaut with a mass of 50 kg is standing on top of a cliff on Mars. The cliff is 20 meters high, and her gravitational potential energy is 3,700 J. What is the value of “g” on Mars?
(g = acceleration due to gravity)

7) A spring with a spring constant of 200 N/m is pulled with a force of 400 N. How far will the spring extend?

8) A spring is pulled with a 100 N force causing it to extend 0.5 meters. What is the spring's spring constant (k)?
