(a)[1]
Describe the skater’s motion from $t = 0$ to $t = 3.0\,\text{s}$.
(b)[2]
Calculate the distance covered by the skater between $t = 0$ and $t = 3.0\,\text{s}$.
(c(i))[1]
State what is meant by deceleration.
(c(ii))[3]
Draw a tangent to the graph at $t = 9.0\,\text{s}$. Use that tangent to calculate the skater’s deceleration at $t = 9.0\,\text{s}$.
