Atoy boat moving at 3.2 m/s accelerates at 6.5 m/s2. how fast will it go after 2.5 seconds?
(number)
(unit)

19.5 m/s

Explanation:

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

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

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

protons in

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
