Question

a car increases its speed from 36 km/hour to 54 km/hour in 10 seconds what is the acceleration​

Answer 1

Answer:

a = 0.5 m/s^2

Explanation:

Acceleration, a = (v - u)/t

u = 36 km/h = 36 * 5/18 = 10 m/s

v = 54 km/h = 54 * 5/18 = 15 m/s

t= 10 seconds

a = (15 - 10) / 10

a = 5/10

a = 0.5 m/s^2
