Explanation:
The motion of the jet ski is an uniformly accelerated motion, so we can find the distance travelled by using the following suvat equation:
where
s is the distance
u is the initial velocity
t is the time
a is the acceleration
For the jet ski in this problem,
t = 35 s
u = 0 (it starts from rest)
Solving for s, we find the distance travelled:
