A 500N car is pulled up to 20m plank to a flat form 5m above the ground by an effort of 150N parallel to the plank. Calculate Velocity Ratio?

Respuesta :

Answer:

4

Explanation:

Velocity ratio is the ratio of distance moved by effort to the ratio of distance moved by load

Velocity ratio = Distance moved by effort / Distance moved by load

Distance moved by effort = 20m

Distance moved by load = 5m

20m / 5m = 4
