Motion — practice question

Fig. 1.1 shows the speed-time graph of an ice skater.
(a)[1]

Explain the meaning of deceleration.

(b(i))[2]

Using Fig. 1.1, work out the distance covered from times $t = 3.0\,\text{s}$ to $t = 6.0\,\text{s}$.

(b(ii))[2]

Using Fig. 1.1, determine the deceleration from $t = 3.0\,\text{s}$ to $t = 6.0\,\text{s}$.

(c(i))[1]

State what happens to the magnitude of the deceleration after time $t = 6.0\,\text{s}$.

(c(ii))[1]

State what happens to the resultant force acting on the skater after time $t = 6.0\,\text{s}$.
