Question

A 1000 kg boat starts at rest and accelerates to 10 m/s in 2 seconds. How fast does the boat accelerate?

Answer 1

Answer:

$5 m/s^2$

Explanation:

The acceleration of an object is given by

$a=\frac{v-u}{t}$

where

v is the final velocity

u is the initial velocity

t is the time it takes for the velocity to change from u to v

For the boat in the problem,

v = 10 m/s

u = 0

t = 2 s

Substituting, we find the acceleration

$a=\frac{10-0}{2}=5 m/s^2$
