Problem

A block is moved in a straight line from

x=0

to

x=4\,\text{m}

. The force acting on the block is

5\,\text{N}

for the first

2\,\text{m}

and

3\,\text{N}

for the next

2\,\text{m}

, both directed along

+x

. Calculate the total work done by the force. a)

8\,\text{J}

b)

26\,\text{J}

c)

16\,\text{J}

d)
