(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A toboggan is initially moving at a constant velocity along a snowy horizontal

surface where friction is negligible. When a pulling force is applied parallel to

the ground over a certain distance, the kinetic energy increases by 47%. By what

percentage would the kinetic energy have changed if the pulling force had been

at an angle of 38° above the horizontal?

2. Relevant equations

w= Fd cos theta

w= 1/2mv^2

3. The attempt at a solution

so Ek = 1.47 Ek intial Ek = kinetic energy
