The diagram shows a block of mass $m$ pulled in a straight line along a horizontal surface by a force $F$. [diagram of block with mass m and force F] The block moves a distance $d$ in time $t$. The average speed at which the block moves is $v$. Which two quantities must be known to calculate the work done?

1. A$F$ and $d$
2. B$F$ and $m$
3. C$F$ and $t$
4. D$F$ and $v$
