Do the following problems on a separate sheet of paper. Draw a picture to accompany each problem, then write your answers 1. You exert a force of 25 newtons while you move a rock 15 meters. How much work did you perform?
2. You move a box 5 meters and perform 900 joules of work. How much force did you apply to the box?
3. You move a box by exerting 45 newtons of force. The total work performed was 2700 joules. How far did you move the box? d. You exert of force of 75 newtons on a rock. You push and you
push, but you can't budge it. You are exhaustedt How much work did you perform?
4. Let's say a small person with a mass of 50 kg walks up two flights of stairs. A heavy person with a mass of 105 kg walks up the same stairs. Who did more work and why? (Hint: Remember
that a newton of gravitational force (weight) is about equal to 100 grams.)
5. You pull a wagon carrying your younger brother 1000 meters (1 km) to the store using 20 newtons of force the whole way. It takes you 15 minutes to get there. How much power did you
generate, in joules per minute? In watts
6. You and a friend move a grand plano across the living room, exerting 25 newtons of force and performing 175 joules of work. It takes you 14 seconds. How far did you move the plano? How
much power did you generate, in watts (joules/sec)?

PLS NO LINKS OR FAME ANSWERS U WILL GET REPORTED I RLLY NEED NELP ON THIS AMD IF I FAIL IT MT GRADE WILL GO DOWN SO PLEASE HELP ME RESPOMD WITH PICTURES PLZ

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
