Question

Consider pushing a cart up each of the four frictionless ramps. The cart begins at rest to the left of each ramp and then ends at rest at the top. Let WA, WB, WC and WD be the amount of work needed to push the cart up each ramp. What describes the relationship between the work required in each case? 1. WA = WB = WC = WD 2. WA < WB = WC = WD 3. WA = WB = WC < WD 4. WA > WB = WC = WD 5. WA > WB > WC > WD 6. WA < WB < WC < WD

What describes the relationship between the work required in each case?

1. WA = WB = WC = WD
2. WA < WB = WC = WD
3. WA = WB = WC < WD
4. WA > WB = WC = WD
5. WA > WB > WC > WD
6. WA < WB < WC < WD
