Question(II) What is the minimum work needed to push a 950kg950-\mathrm{kg} car 510 m up along a 9.09.0^{\circ} incline? Ignore friction.

Studdy Solution
Calculate the work done to move the car up the incline:
W=Fparalleld W = F_{\text{parallel}} \cdot d
where d=510m d = 510 \, \text{m} .
W=1456N×510m W = 1456 \, \text{N} \times 510 \, \text{m}
W742560J W \approx 742560 \, \text{J}
The minimum work needed to push the car up the incline is:
742560J \boxed{742560 \, \text{J}}
