Question

A car is starts from rest attains a velocity of 72km/h in 5min find acceleration of car?​

Answer 1

Answer:

1/15 m/s²

Explanation:

Initial Velocity (u) = 0 m/s

Final Velocity (v) = 72 km/h = (72)(1,000)m/(3,600)s = 72,000/3,600 = 20 m/s

Time (t) = 5 minutes = (5)(60) s = 300 s

v = u + at

20 = 0 + (a)(300)

a = 1/15 m/s²
