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((:

How long will it take a driver to drive 300 miles by maintaining a constant speed of 60 miles per hour

Time = Distance/Speed = 300 miles/60 mph = 5 hours

A force of 20 N gives a ball an acceleration of 4.0 ms on a level frictionless surface what is the mass of the ball

F=ma

m=F/a

m=20/4.0

m=5Kg
