A student does 300 joules of work pushing a cart 3.0 meters due east and then does 400 joules of work pushing the cart 4.0 meters due north the total amount of work done by the student is?
Work is a scalar quantity, not dependent upon direction. Use simple addition (not a vector sum) to calculate the total work done on the cart: 300. J + 400. J = 700. J.
How much work in joules is performed when a force of 800.0 N is exerted while pushing a crate across a level floor for a distance of 1.5 meters?
We must assume that the force pushes parallel to the floor.Work = (force) x (distance) = (800) x (1.5) = 1,200 newton-meters = 1,200 joules
A ramp is 30 meters long and 5 meters high 200 newtons of force must be applied by the mover to push a 1000 newton piano up the ramp?
What is the amount of work accomplished by the ramp? - 5000 joules What is the amount of work done by the mover? - 6000 joules What is the efficiency of the ramp? - 83%
Are watts measured by Joules divided by meters or Joules divided by seconds?
joule/sec
If a student drops a book having a gravitational potential energy of 5 joules from a height of 1.1 meters what is the mass of the book?
The book has a mass of 0.46kg
How do you convert cubed meters to Gigajoules?
You don't. Cubic meters is a measure of volume; joules or gigajoules is a measure of energy.You don't. Cubic meters is a measure of volume; joules or gigajoules is a measure of energy.You don't. Cubic meters is a measure of volume; joules or gigajoules is a measure of energy.You don't. Cubic meters is a measure of volume; joules or gigajoules is a measure of energy.
What units are work measured in?
Joules or newtons*meters
How do you convert meters to joules?
1.097*10^7meters
If 10 joules in 20 seconds how many newtons?
You can't calculate the force from the rate at which work is done.10 joules in 20 seconds could be:-- 1 newton pushing along at 50 centimeters per second, or-- 0.1 newton pushing 5 meters per second, oran infinite number of other possibilities.From the data given in the question, all we know is that the 'power' is 1/2 watt.
How many joules of work would be accomplished if you move a 200 kg slug 10 meters?
2000 joules
What is the formula to find joules?
To find joules, you have to multiply the force or newtons by distance in meters.
Newtons times meters this is know as what?
joules
