Motion — practice question
A diver in the sea is using breathing apparatus that emits gas bubbles. Figure 1.1 shows bubbles moving up towards the surface. They begin from rest and, initially, rise with constant acceleration. Figure 1.2 is an unfinished speed-time graph for one of the bubbles from time $t=0\,\text{s}$ to $t=10\,\text{s}$.
