Question

A toy boat moving at 3.2 m/s accelerates at 6.5 m/s2. How fast will it go after 2.5 seconds?

(number)
(unit)

Answer 1

19.5 m/s

Step-by-step explanation:

The boat is moving with a uniform accelerated motion, therefore we can use the following suvat equation:

`v=u+at`

where :

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time

For the boat in this problem,

u = 3.2 m/s

`a=6.5 m/s^2`

Substituting t = 2.5 s, we find the final velocity of the boat:

`v=3.2 + (6.5)(2.5)=19.5 m/s`
