(High school physics) 1a) How much work is done in lifting a 25kg Christmas gift to a height of 15m? 1b) How much work is needed after lifting the Christmas gift, to carry it horizontally 250 m?
Imagine that there is a heavy box sitting on the floor that you want to lift up & carry across the room. A. How do the forces compare: i. The force initially needed to lift the box off the ground ii. The force needed to continue lifting the box (vertically) in order to then carry it across the room? B. Explain why this makes sense to you.
A hydraulic lift is used to jack a 950-kg car 42 cm off the floor. The diameter of the output piston is 17 cm , and the input force is 360 N . What is the area of the input piston? What is the work done in lifting the car 42 cmcm ? If the input piston moves 13 cmcm in each stroke, how high does the car move up for each stroke? How many strokes are required to jack...
what is The total work done in lifting a typical high school physics textbook a vertical distance of 0.10 meter
Student A lifts a 50.0-newton box from the floor to a height of 0.40 meter in 2.0 seconds. Student B lifts a 40.0-newton box from the floor to a height of 0.50meter in 1.0 second. Compared to student A, what does student B do?the same work butdevelops less powermore work but develops less powerthe same work but develops more powerless work but develops morepower
if you lift a 50 lb barbell 6 foot off the floor, how much work do you do? by how much do you charge change the barbells potential energy? if you drop the barbell from 6-foot what is its kinetic energy just before it hits the floor?
