Question

I'm walking 1.6m/s to 7-11 and it started to rain so I sped up to 2.7m/s in 1.2

Answer 1

Answer:

Explanation:

$a = \frac{v_f-v_0}{t}$ which is the final velocity minus the initial velocity in the numerator, and the change in time in the denominator.  For us:

$a=\frac{2.7-1.6}{1.2}$ so

a = .92 m/s/s (NOT negative because you're speeding up)
