(a)[2]
Describe, without calculation, how the stone’s speed changes from $t = 0$ to $t = 3.0\,\text{s}$ using Fig. 2.1.
(b(i))[3]
Assume air resistance is negligible, so the stone moves with constant acceleration. Calculate the stone’s speed at $3.0\,\text{s}$.
(b(ii))[3]
Calculate the distance covered from $t = 0$ to $t = 3.0\,\text{s}$.
(b(iii))[2]
Calculate the displacement from $t = 0$ to $t = 3.0\,\text{s}$ and state its direction.
(c)[3]
On Fig. 2.2, draw how the stone’s velocity $v$ varies with time $t$ from $t = 0$ to $t = 3.0\,\text{s}$.
(ii)[3]
the distance travelled between $t = 0$ and $t = 3.0\,\text{s}$.
(iii)[2]
the displacement from $t = 0$ to $t = 3.0\,\text{s}$. Give the direction of the displacement.
