A bicycle is an example of what machine

A bicycle is an example of a complex machine, consisting of interacting simple machines.

What factor prevents a machine from operating at 100 percent efficiency

Friction((:

The value of the impulse equals the force x the

The value of the impulse equals the the force times the time.

A ramp is 30 meters long and 5 meters high 200 newtons of force must be applied by the mover to push a 1000 newton piano up the ramp

What is the amount of work accomplished by the ramp? - 5000 joules

What is the amount of work done by the mover? - 6000 joules

What is the efficiency of the ramp? - 83%
