Question

The car started with an initial speed of 5m/s, and achieve the final speed of 10m/s in five-second, then what is the acceleration of the car? ​

Answer 1

u = 5m/s

v = 10m/s

t = 5 seconds

Using the 1st equation of motion,

v = u + at

10 = 5 + a(5)

10 - 5 = 5a

5 = 5a

a = 5/5

a = 1

Hence acceleration is 1m/s²
