Explain why you do not need to calculate the work done by the
normal force on the cart or the work done by tension on the cart or
the hanging mass to evaluate if the total energy of the
cart-hanging mass-Earth system is conserved. (See the system
below). 
Homework Answers
Normal force always perpendicular to displacement. So w zero.
Tension acts in opp directions on cart n mass. So Work by tension on cart eqal n opp to work by it on hanging mass. So total work by tension on system is zero.
so, they need not be calulated

M i ques more work: Stretching a stiff spring a certain distance or stretching a weak spring the same distance? Defend your answer. - Stretching a stiff spring. This is simply because a stiff spring is more resistant to movement which requires more force or work to move it. 3. An object that has a small mass and...

You create a lab to investigate the concept of work and energy. Figure 1 is a sketch of the experiment setup. The system can be considered frictionless. You have found the combined mass of the cart & force sensor to be 1.20[kg]. The cart is initially at rest. After attaching a 200[g] mass to the end of the string, the cart starts moving. The distance between the floor and the bottom of the hanging mass is initially 80.0[cm]. Assume the...

REMARKS The normal force ni, the gravitational force mš, and the upward component of the applied force do no work on the sled because they're perpendicular to the displacement. The mass of the sled didn't come into play here, but it is important when the effects of friction must be calculated and in the work-energy theorem. QUESTION How does the answer for the work done by the applied force change if the load is...

7. Carrie's group is analyzing the motion of a cart that moves up a ramp. Carrie claims that when the cart slows down the kinetic energy is negative. She justifies this claim by stating that "the work-energy theorem for an object says that when a force pushes an object the kinetic energy increases but now the force is pulling the object." Andrea disagrees and claims that the kinetic energy of the cart is never negative anywhere on the ramp but...
