Question

1. A sailboat accelerates uniformly from 3.0 m/s to 12.0 m/s at a rate of 1.5 m/s2. What distance does the boat travel?​

Answer 1

Answer:

45 m

Explanation:

Use the equations of motion.

We know that:

S= the unknown

U=3 m/s

V=12 m/s

A=1.5 m/s

T= we won't need it

The equation used: $v^2=u^2+2as$

Subsitute the values: $12^2=3^2+2*1.5*s$

Solve the equation:

$144=9+3s$

$135=3s$

$s=45 m$
