Question

a car traveling at 60m/s accelerates at 2 m/s for 30s.calculate how far it has traveled during this time​

Answer 1

Answer:

2,7 km

Explanation:

You should remember from theory that

$s=s_0 + v_0\Delta t + \frac12 a(\Delta t)^2$. Let's substitute values, remembering that we are interested in the difference in position $\Delta s = s-s_0$

$\Delta s = 60(30) +\frac12 2 (30)^2 = 2700m$

Answer 2

Answer:

it's average acceleration is 12 mph
