Work, Force and distance& Momentum Problems

The equation for work is shown.  Work = Force x Distance

• 5 joules
• 20 joules
• 45 joules
• 500 joules

A student did 60 Newton-meters of work by pulling a box 6 meters.  Approximately how much force did the student apply? 
F = W/d

• 5 newtons
• 10 newtons
• 20 newtons
• 180 newtons

A student pushes a wheelbarrow with a force of 80 newtons over a distance of 10 meters.  How much work is done by the student?
W = F x d

• 8 newton-meters
• 70 newton-meters
• 90 newton-meters
• 800 newton-meters
