Suppose you needed to push a 1,500-N sofa up a frictionless ramp with a 30° angle. How much force would you have to apply to the
sofa?Show your work below.
1 answer:
Answer:
1299N
Explanation:
GIven data
Weight W= 1500N
Angle Ф= 30°
The applied force up the frictionless ramp is gotten by applying the formula below
F= WcosФ
substitute
F=1500 cos 30
F = 1500*0.8660
F= 1299N
Hence the applied force is 1299N
