How do you find the time of an object when it hits the ground?

Divide the falling distance by 16. For example, if the object will fall 128 feet, divide 128 by 16 to get 8. Calculate the square root of the Step 2 result to find the time it takes the object to fall in seconds.

How do you determine how long an object is in the air?

Use the vertical motion model, h = -16t2 + vt + s where v is the initial velocity in feet/second and s is the height in feet to calculate how long the basketball will be in the air for.

How long does the projectile remain in the air?

The time for projectile motion is completely determined by the vertical motion. So any projectile that has an initial vertical velocity of 14.3 m/s and lands 20.0 m below its starting altitude will spend 3.96 s in the air.

What is the speed of an object at ground level?

An object at ground level is projected outwards with a speed of 20 m.s at an angle 45 degrees above the horizontal over level ground. Which is true of the object accretion?

What is the final velocity when a ball is thrown upward?

The height where the velocity becomes zero which is the maximum height the ball went upward, say is H. And for this upward movement, the final velocity v2 is 0 because the ball has stopped at the end of this upward traversal. Why an object thrown upwards comes down after reaching a point?

What is the distance traveled by a projectile being affected by gravity?

The equation for the distance traveled by a projectile being affected by gravity is sin(2θ)v 2 /g, where θ is the angle, v is the initial velocity and g is acceleration due to gravity. Assuming that v 2 /g is constant, the greatest distance will be when sin(2θ) is at its maximum, which is when 2θ = 90 degrees.

Why does an object thrown upwards come down after reaching a point?

Why an object thrown upwards comes down after reaching a point? When an object is thrown with certain initial velocity (say V), it gains a Kinetic energy at that moment of throwing. As it moves upwards from its initial position (wherefrom it’s thrown) and gains height, its potential energy rises.
