Question

How do you determine final velocity in projectile motion

Answer 1

To determine the final velocity in projectile motion, resolve the motion into its horizontal and vertical components. Use the equation v = vx + at, where v is the final velocity, vx is the horizontal velocity, a is the acceleration due to gravity, and t is the time of flight.

Step-by-step explanation:

In projectile motion, the final velocity can be determined by resolving the motion into its horizontal and vertical components. The horizontal velocity remains constant throughout the motion, while the vertical velocity changes due to the effect of gravity. To find the final velocity, you can use the equation v = vx + at, where v is the final velocity, vx is the horizontal velocity, a is the acceleration due to gravity, and t is the time of flight.

Answer 2

The final vertical velocity is given by Equation 4.21: vy=v0y−gt
