Question

A person starts at rest and accelerates at a uniform rate of 3.2 ms² for 3.0 seconds. What distance does this person cover in that time?

Answer 1

14 m

Step-by-step explanation:

Given:

u = 0 m/s

a = 3.2 m/s²

t = 3.0 s

Find: s

s = ut + ½ at²

s = (0 m/s) (3.0 s) + ½ (3.2 m/s²) (3.0 s)²

s = 14.4 m

Rounded to two significant figures, the person moves 14 m.
