(a(i))[1]
Define force
(a(ii))[2]
Find the block's change in momentum from time $t = 0$ to time $t = 3.0\,\text{s}$.
(b(i))[2]
Describe and explain the block's motion from time $t = 3.0\,\text{s}$ to time $t = 6.0\,\text{s}$.
(b(ii))[3]
Force $X$ gives a total power of $2.0\,\text{W}$ while moving the block from time $t = 3.0\,\text{s}$ to time $t = 6.0\,\text{s}$. Calculate how far the block moves in this time interval.
(c)[2]
The block is stationary at time $t = 0$. On Fig. 3.3, draw a sketch showing how the momentum of the block varies with time $t$ from $t = 0$ to $t = 6.0\,\text{s}$. You do not need to include numerical momentum values.
