If a car increases its velocity from 0 to 60 km/h in 10 seconds, what its acceleration is?
Acceleration is the rate of change of velocity.
Answer: If a car increases its velocity from 0 to 60 km/h in 10 seconds, its acceleration is 21600 km/h2.
Let's solve this question step by step.
Explanation:
Given: Initial velocity(u) = 0km/h
Final velocity(v) = 60 km/h
Time taken(t) = 10 s
Convert time from second to hours
10/3600 h = 1/360 h.
Putting these values in Newton’s first equation of motion,
v = u + at
⇒ 60 = 0 + a × 1/360
⇒ 60 × 360 = a
⇒ a = 21600 km/h2
Hence, the acceleration of the car is 21600 km/h2.
