Question

a) Derive the kinematie equation of motion
b) write the kinematie equation for a freely falling body
​

Answer 1

Answer:

Whether explicitly stated or not, the value of the acceleration in the kinematic equations is -9.8 m/s/s for any freely falling object. If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s.
