An object is thrown upward from 1 m above the ground. It travels vertically up, reaches a maximum height of 2.5 m above ground
An object is thrown upward from 1 m above the ground. It travels vertically up, reaches a maximum height of 2.5 m above ground, falls back down, and is caught at exactly the same position it was thrown 1 s after it was thrown. What was the average velocity of the object? Click the answer you think is right 1.5 m/s 0 m/s 3 m/s
