A bully stole my phone and threw it upward into the air, the phone falls after .80 seconds. At what initial velocity did the mean bully throw the phone?
Use 9.8 m/s as Earth's acceleration due to gravity Round off to 2 decimal places
The answer is 3.92.

Initial Velocity = -Vf + gt = 0 + (9.8) (0.40) = 3.92 m/s
