Power=(Force X distance) / (time)
P= (13N x 3m) / (5 sec)
P= 7.8 Watts
The object will move a total distance of 80 meters, which is calculated by multiplying the speed (10 m/s) by the time (8 seconds).
Work done = force * distance > Work done / time = power
two watts a second
To find the time it takes to move the object, you can use the formula: time = work/power. First, calculate the work done by multiplying the force (mass*gravity) by distance (11kg * 9.81m/s^2 * 6m). This gives you the work done in joules. Then divide this work by the power (42W) to find the time in seconds.
To find how many seconds it would take for the object to move to the 150.0 meter mark, you would need to locate the point on the graph where the distance is 150.0 meters. Then, you can determine the corresponding time value on the x-axis to find the time it takes for the object to reach that point.
The power needed would depend on the force required to move the piano and the distance it is moved in 5 seconds. Without knowing these factors, an accurate estimate cannot be provided.
Work is the result of applying force to an object and moving it over a distance. Power is the rate at which work is done, so the more power you use to move an object, the more work you are able to perform in a given amount of time.
You do work
The use of force to move an object some distance is called work. Work is calculated by multiplying the force applied to an object by the distance the object moves in the direction of the force. Work is measured in joules.
when you exert a force on an object that causes the object to move some distance.
That would be distance.
