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

seconds. What is my acceleration?
a=(vf-viyt
-0.92m/s2
O 01.1m/s2
0.92m/s2
1.1m/s2

Answer 1

Step-by-step explanation:

`a = (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=(2.7-1.6)/(1.2)` so

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