Answer:
Given:
Initial Velocity (Vi)- 0m/s
Final Velocity (Vf)- 25m/s
Time-30 seconds
Unknown: Acceleration(a)
Formula: a=(v1-v0)/t
Solution and Answer: a=(25-0)/30=0.83 m/s^2
(projectile motion)
Using the data from the table, calculate the final velocity of the ball using the formula vf = at
since vi = 0. Try also calculating final velocity using the formula vf = 2Agh. Compare your
