Velocity Calculation  

Initial Velocity :
v_{0} = v − at
Acceleration :
a = v − v_{0}/t
Time :
t = v − v_{0}/a
Where,
v = Velocity,
v_{0} = Initial Velocity
a = Acceleration,
t = Time.
Example:
Calculate the velocity of an object for the given details.
Initial Velocity (v_{0}) = 10 m/s
Acceleration (a) = 5 m/s^{2}
Time (t) = 15 sec
Solution:
Apply Formula:
v = v_{0} + at
v = 10 +5*15
v = 10+75
v = 85 m/s
Velocity (v) = 85 m/s
