Questions: 1. No. This is because the force acting on the cart by tension is a non-conservative force. 2. No. This is because friction is a non-conservative force. If E initial was on the x axis and E final was on the y axis then the slope would be less than one because E final would be less than E initial . 3. If the cart was given an initial velocity down the ramp each time then the y

Unformatted text preview: intercept would not be zero but it would be the mass of the cart times the velocity squared divided by 2. This means even at a distance of zero from the photo-gate timer, the cart would have kinetic energy because it would already be moving at a velocity not equal to zero....
