Your answer

13. A child performs 10J of work in lifting a box 1 m in 2 seconds. How much

power did the child apply to the box? (Do not include units with your answer.)

P=W/t *

Your answer

Answer 1

Answer:

Explanation:

Well they told you the exact formula to use. Work is the force multiplied by  the distance through which its applied.

W = (20N)(35m)

= 700 Joules

13.) Power is the amount of work done over the time through which the work is being done.

P = W/t

= 10J/2s

= 5J/s
