A 9 kg sled is initially at rest on a horizontal frictionless road. The sled is pulled a distance of 3.1m by a force of 45N applied to the sled at an angled of 30 degrees to the horizontal. Find the change in the kinetic energy of the sled
Homework Answers
chenge in kinetic energy = work done by net force = F*S*cos(30) = 45*3.1*cos(30) = 120.81 J
change in K.E K2-K1=F.s
K2-K1=Fcos(theta)*s
=45*cos(30)*3.1
=120.81 J....is answer
