Answer:
It will take 0.014 hour or 50.4 seconds to reach a speed of 120 km/h
Explanation:
We are given:
Initial speed of car = Vi = 50 km/h
Final Speed of car = Vf = 120 km/h
Acceleration of car = a = 5000 km/h²
Time taken = t =?
Using 1st equation of motion;
Vf = Vi + at
t = (Vf - Vi)/a
t = (120 km/h - 50 km/h) / 5000 km/h²
t = 0.014 h
t = (0.014 h)(3600 sec/1h)
t = 50.4 sec
