Calculate the force used if 108J of work done is moving a wrapped present 9M

F = 12 N

Explanation:

Mechanical Work

Mechanical work is the amount of energy transferred by a force. It's a scalar quantity, with SI units of joules.

Being F the force vector and s the displacement vector, the work is calculated as:

W = F.s

If both the force and displacement are parallel, then we can use the equivalent scalar formula:

W=F.s

When the value of the work is known and we need to find the force, we solve the above equation for F:

The wrapping present is moved by s=9 m doing W=108 J of work. The force used is:

F = 12 N

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.
