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

Step-by-step 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.
