Determine the approximate force (n) used to pull a sled up a 400 m hill using 1900 j of work. 0.2n 800,000n 500n 5n

The work done to pull the sled up to the hill is given by

where
F is the intensity of the force
d is the distance where the force is applied.

In our problem, the work done is  and the distance through which the force is applied is , so we can calculate the average force by re-arranging the previous equation and by using these data:

Aliquid is an answer i hope this

Answer(b) 60 miles per hour;
