If there is uniform acceleration, the final velocity is just the initial velocit

Question

If there is uniform acceleration, the final velocity is just the initial velocity plus the acceleration times the time of the acelleration. The final speed is the intital speed plus the gain of speed or the inital speed plus [(rate of gain of speed) times (the time under which the object gains speed)] Thus in algebraic form, if a is acceleration, t is time, and v0 is the initial velocity and v is the final velocity, then the speed at time t is just given by the relationship v = v0 + at An object fall freely from rest on a planet where the acceleration due to gravity is 20 m/s/s. After 5 seconds, the object will have a speed of Question 9 options: 5 m/s 10 m/s 20 m/s 50 m/s 100 m/s

Explanation / Answer

20 m/s
