A sled with a mass of 5.80 kg is pulled along the ground
Chapter 7, Problem 70GP(choose chapter or problem)
IP A sled with a mass of is pulled along the ground through a displacement given by \(\mathrm {\vec{d}=(4.55\ m)\hat{x}}\). (Let the
axis be horizontal and the
axis be vertical.) (a) How much work is done on the sled when the force acting on it is \(\mathrm {\vec{F}=(2.89\ N)\hat{x}+(0.131\ N)\hat{y}}\)? (b) How much work is done on the sled when the force acting on it is \(\mathrm {\vec{F}=(2.89\ N)\hat{x}+(0.231\ N)\hat{y}}\) (c) If the mass of the sled is increased, does the work done by the forces in parts (a) and (b) increase, decrease, or stay the same? Explain.

ANSWER:
Step 1 of 4
Part (a)
A sled of mass m is pulled by a force through a distance. We are going to find the work done by the force. The force has both vertical and horizontal components.
The mass of the sled m = 5.80 kg
The displacement vector
The force
