Question

Luke pulls a sled using a force of 65 N for a distance of 25 m across level ground. The rope Luke pulls forms an angle of 25° with the ground. About how much work does Luke do on the sled? 250 J 690 J 1,500 J 1,600 J

Answer 1

The answer is c 1,500 its right 100%

Answer 2

Answer:  1,500 J

Explanation:

The work done by Luke is given by:

$W=Fdcos \theta$

where

F = 65 N is the force applied by Luke

d = 25 m is the displacement of the sled

$\theta=25^{\circ}$ is the angle between the direction of the force and the displacement

Substituting numbers into the formula, we find

$W=(65 N)(25 m)(cos 25^{\circ})=1473 J$

So, approximately 1500 J.
