Final answer:
If the initial speed is increased by 3, the hang time would not change. Hang time is primarily determined by the initial vertical velocity and gravitational acceleration.
Step-by-step explanation:
If the initial speed is increased by 3, the hang time would not change. Hang time refers to the amount of time an object stays in the air during a jump or projectile motion. It is primarily determined by the initial vertical velocity and gravitational acceleration.
Increasing the initial speed by 3 would only affect the object's horizontal motion, not its vertical motion. The hang time is determined by the object's vertical motion, which is determined by the initial vertical velocity. Therefore, the hang time would remain the same.
It's important to note that other factors such as air resistance and the angle of projection can also affect the hang time.
