Determine the amount of force needed to push a 500lb motorcy

Determine the amount of force needed to push a 500-lb motorcycle up a ramp that is inclined at a 35 degree angle.

Solution

the minimum magnitude of force must equal the component of weight acting downhill considering the friction negligible.

m= 500 lb *0.454 kg/lb = 227 kg

This gives: F = m*g*sin(theta) = 227 x 9.8 x sin(35degrees) = 1275.978 N acting \'uphill\'
