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

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

When a golf club strikes a golf ball the force exerted by the ball on the club depends on

the mass of the ball and club and the velocity of the club

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
