A1000 kg boat starts at rest and accelerates to 10 m/s in 2 seconds. how fast does the boat accelerate?
5 points
20,000 m/s^2
5,000 m/s^2
50 m/s^2
100 m/s^2
200 m/s^2

Explanation:

The acceleration of an object is given by

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

v=ir = 3x15 =45 v

compass can be used day and night, cloudy or sunny
