What is the minimum work needed to push a 950-kg car 710 m up along a 9.0° incline? Ignore friction.
Work needed to push the car along 9° incline.
Answer to Problem 5P
Solution:
1.03 ×106 J
Explanation of Solution
According to the diagram the force required to push the car along a 9° incline will be
Given:
Mass of the car, m=950 Kg. Distance, d = 710 m. Incline angle, θ=9°.
Formula used:
Where “F” is the Force required to push the car
“m” is the mass of the car
“a” is the acceleration or gravity force (9.8 m/s2)
Where “F” is the Force required to push the car
“W” is the work done
“d” is the distance.
Calculation:
Force required pushing the car
---------------(1)
Work done on the car
-------------------(2)
By using equation (1)and (2)
