Alex rides on a bike that starts from rest and accelerates to a speed of 20 m/s in 8 seconds. What is Alex’s acceleration? with steps please

Sagot :

Answer:

2.5m/s

Explanation:

a = [tex]\frac{(vf - vi)}{t}[/tex]

vf = final velocity = 20m/s

vi = initial velocity = 0m/s (alex is starting "at rest")

a = acceleration =

t = time = 8s

a = [tex]\frac{(20-0)}{8 }[/tex] = 2.5m/s
