Answer 1

Displacement = 72m

Acceleration = 4
`m/s^(2)`

Step-by-step explanation:

The jet ski increases its speed from zero to 24 m/s in 6 seconds.

We are supposed to find the displacement and its acceleration rate.

Displacement is the distance it covers in this time interval.

Acceleration is the rate of increase of speed.

Acceleration =
`(change in velocity)/(time)`

Acceleration =
`(24 - 0)/(6)`

Acceleration = 4
`m/s^(2)`

According to equation of motion ,

`v^(2)-u^(2) = 2* a* s`

`24^(2) - 0 = 2* 4* s`

s =
`(576)/(8)`

Displacement , s = 72 m
