Calculate the acceleration for the following data: Initial Velocity=20 m/s, Final Velocity: 60 m/s, Time: 10 s

a = 3 [m/s²]

Explanation:

To solve this problem we must use the following equation of kinematics.

where:

Vf = final velocity = 60 [m/s]

Vo = initial velocity = 20 [m/s]

a = acceleration [m/s²]

t = time = 10 [s]

Now replacing these values we have:

60 = 20 + (a*10)

60 - 20 = 10*a

30 = 10*a

a = 3 [m/s²]
