A car increases its velocity from 0 m/s to 9 m/s in 6 seconds. Calculate its acceleration in n m/s/s. Round your answer to one decimal place.

1.5 m/s/s

Explanation:

This problem can be solved using equation of motion given below

where v is the final velocity

u is the initial velocity

t is the time

given

final velocity = 9 m/s

initial velocity = 0 m/s

t = 6 seconds

lets substitute these value in v = u + at

9 = 0 + a*6

=> 9 = 6a

=> a = 9/6 = 3/2 = 1.5

Thus, acceleration is 1.5 m/s/s
