Final answer:
Tommy used a force of 15 Newtons to push the pencil over 1 meter, as calculated using the formula F = W/d with the given values of work (W) being 15 Joules and distance (d) being 1 meter.
Step-by-step explanation:
The student asked how much force was used to push a pencil when 15 Joules of work was done to push it over a distance of 1 meter. The formula to calculate force when work and distance are known is F = W/d, where F is the force in Newtons (N), W is the work in Joules (J), and d is the distance in meters (m). we can use the formula F = W/d, where F is the force, W is the work, and d is the distance. In this case, Tommy did 15 Joules of work to push the pencil over 1 meter. Plugging these values into the formula
Substituting the given values into the formula gives us F = 15 J / 1 m, which simplifies to F = 15 N. Therefore, Tommy used a force of 15 Newtons to push the pencil over a distance of 1 meter.
