Question

A corvette can accelerate during high speeds at about 2.0 m/s2. At this rate how long does it take the car to accelerate from 80 km/h to 160 km/h?

Answer in seconds. Round to two decimal places.

Answer 1

11.11 s

Step-by-step explanation:

Given:

u = 80 km/h = 22.22 m/s

v = 160 km/h = 44.44 m/s

a = 2.0 m/s²

Find: t

v = u + at

44.44 m/s = 22.22 m/s + (2.0 m/s²) t

t = 11.11 s
