An object accelerates from rest with a constant acceleration of 7.5 m/s2. How fast will it
Serhud [2]

Answer:

13.4 m/s

Explanation:

Given:

Δx = 12 m

v₀ = 0 m/s

a = 7.5 m/s²

Find: v

v² = v₀² + 2aΔx

v² = (0 m/s)² + 2 (7.5 m/s²) (12 m)

v ≈ 13.4 m/s

State: the units for acceleration are?
krok68 [10]

A unit of acceleration needs a unit of length in the numerator
and a squared unit of time in the denominator.

Example:    meters / second²
                    feet / minute²
                    smoots / hour² 
                    furlongs / fortnight² .

Ideally, in order to completely describe an acceleration vector,
you also need to state a direction.
