Question

Suppose your vehicle is moving 12m/s as it crosses the 7m line. It took 6 seconds to get to the 7m line. What was its acceleration?

Answer 1

3.61 m/s²

Step-by-step explanation:

Given:

v = 12 m/s

x = 7 m

x₀ = 0 m

t = 6 s

Find:

a

x = x₀ + vt - ½ at²

7 m = 0 m + (12 m/s) (6 s) - ½ a (6 s)²

a = 3.61 m/s²
