The work Jake takes to climb the stairs while running, is 1000 joules, and the time he takes to climb them, is 5 seconds. You get the power by calculating 1000 joules between the 5 seconds and the result will be 200 w. P=w/t
It can't be possible! I'm gonna be late. My mom told me not to bring this shoes but I didn't listen to her.
I wanna still his shoes!
Gotta keep running!
What do you think? I took your shoes!
You! Taste my fist!
Frank is dragging Jake horizontally across the floor by a 100 N force, acting parallel to the floor. To know the work done by the force of Frank in moving Jake through a distance of 8 m to the bathroom, is from multiplying the force by the distance and by the angle (in this case cos 0) So the work will be 800 J (W=F Cos 0)
I'm gonna drag him here so no one suspects!
Here I'm gonna take his shoes and put him mine!
Frank lifted Jake whose mass is of 65 kg, a height of 1.5 m. So the gravitational potencial energy gained by the mass, comes from multiplying the mass by the gravity which is 9.8 N/kg, by the height. So the result is gonna be 955.5 J
