Multiply the power (1,800 watts) by time (1,200 seconds) to get 2,160,000 joules (or 2.16 MJ)
Answer:
Explanation:
From the question we are told that:
Frictional force 
Coefficient of kinetic friction 
Generally the equation for Normal for is mathematically given by
Therefore
Answer:
- It can put out more force than the input force by decreasing the distance through which force is applied.
- It can apply a force to an object in a different direction than the force applied to the machine.
Explanation:
Assuming the machine is a simple machine, such as a lever or pulley, the machine will not do any more work than is put into it. However, it can change the magnitude or direction (or both) of the input force required to achieve a particular output force.
Because the machine does not increase the work done, if the output force is greater, the output distance must be less.
The applicable observations are ...
- It can put out more force than the input force by decreasing the distance through which force is applied.
- It can apply a force to an object in a different direction than the force applied to the machine.
