1. A block is pulled 7.00 meters along a horizontal surface
with a constant 30.0 newton force. Calculate the work
done on the block.
[210 J]
2. A force of 50 newtons is used to do 5.0 x 102 joules of work
on an object. Over what distance was this force applied?
4. A 5.00 kilogram block is pulled 2.0 meters along a
horizontal, frictionless surface using a force of 100
newtons at an angle of 20.0° above horizontal as shown
in the diagram below.
Determine the amount of work done on the block as it is
moved.
100 N
