a. How long does it take the car to come to a stop from a velocity of 30 m/s?

Respuesta :

Answer:

5s

Explanation:

initial distance: 0 m

distance: ? (we don't know)

initial velocity: 0 m/s

velocity: 30 m/s

acceleration: 6 [tex]m/s^{2}[/tex]

time: ? (we are looking for)

v = v0 + at

plug the numbers in:

30 = 0 + 6(t)

= 30 = 6t

= t = 5

5s
