A child pulls a 13 kg sled across the snow at a constant 1.6 m/s [N] applying a force of 51 N [N 25 deg U]. How much work have they done after pulling for 44 m? Round answers to the nearest whole number.

Question

m=13kg
Vcon=1.6m/s
F=51N
d=44
cos theta=25

W=Fdcostheta?

I don't know how to this because I did a similar question, plugged everything in and got it wrong.

Answer 1

yes, that is it

Answer 2

k thanks :)

Answer 3

i realized the last time when i got it wrong, I put in;

w=Fdcos20
=51(44)(20)

when i should've put;

w=51(44)(cos20)
