Question

A jet ski accelerates towards a ramp at 2.5 m/s/s for 35 s until it finally flies off the water. Determine the

distance the jet ski traveled before lifting off the water.

Answer 1

1531 m

Step-by-step 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:

`s=ut+(1)/(2)at^2`

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,

`a=2.5 m/s^2`

t = 35 s

u = 0 (it starts from rest)

Solving for s, we find the distance travelled:

`d=0+(1)/(2)(2.5)(35)^2=1531 m`
