if a car can go from 0 to 60 mi/hr in 8 seconds, what would be its final speed after 5.0 seconds if its starting speed were 50mi/hr

• science -

V1=60mi/h * 1600m/ml * 1h/3600s=26.7m/s

Vo = (50/60) * 26.7m/s = 22.22 m/s.

a = (V1-0)/t = (26.7-0)/8 = 3.33 m/s^2

V = Vo + a*t = 22.22 + 3.33*5=38.87 m/s
= Final speed.
