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.
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 do you calculate the mass of an object that has a potential energy of 180 joules and rest at the top of a hill 15 meters from the ground?
Calculate the work done by a 2.4 N force pushing a 400 g sandwich across a table 0.75 m wide?
The 400g is a variable that is meant to fool you and doesn't doesn't apply to the formula. We use the W=Fs formula, Where W= Work (joules), F=Force (Newtons) and s=Displacement (meters). W=? F=2.4N s=0.75 m W=Fs W=2.4x0.75 W=1.8 J

How to calculate rate of energy transfer in Joules per second or Joules per minute?
You can divide any unit of energy by any unit of time; but the standard SI unit is Joules / second, and has the special name "Watt".
When calculating power what 2 pieces of information are needed?
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
Calculate number of joules in 1kwh?
1 Watt = 1 Joule/second 1 kilowatt = 1000 Watts = 1000 Joules/second 1 hour = 60 minutes = 3600 seconds 1 kWh = 1000 (Joules/second) * 3600 (seconds) = 3,600,000 Joules = 3.6 MJoules
