The velocity of a car is increased by 60km/hour in 1min starting from rest. what is its acceleration?
Answers
Answer:
Hence, The average velocity is 8.33 m/s, the acceleration is 0.278 m/s² and the distance traveled in first 1 min is 999.6 m.

Answer:
0.27 m/s^2
Explanation:
Acceleration = Change of Velocity with time i.e. {Final-Initial (Velocity)}/Time
SI Unit of Acceleration m/s^2 or ms^-2
Since the car started from rest, its initial velocity = 0
Given Final Velocity = 60 km/h
Converting 60 km/h into m/s (You can use the 5/18 formula, but for your convenience I am doing it this way)
60km x 1000 = 60000m
1hr x 60 = 60min
60min x 60 = 3600 secs
Final Velocity = 60000/3600 = 16.666666... or 16 2/3 m/s (Let's assume it to be 16.66 m/s for the convenience of calculation)
Using the derived acceleration formula (described above):
Vf - Vi/T
Putting the values:
16.66 - 0 / 60 = 16.66/60 = 0.27 m/s^2 (approximately)
Hence, the acceleration is 0.27 m/s^2
