Ignoring drag:
h=32.7*t-0.5*g*t2
Where g is about equal to 32.2 ft/sec2

What does vt mean in the vertical motion formula?
it means initial upwards height times time in seconds
Question-1 A body is thrown vertically upwards The distance st above the ground after t seconds is given by st 20t-5t2 meters?
The equation for vertical motion is y = v0t + .5at2. y is vertical displacement v0 is initial vertical velocity a is acceleration (in meters, normal gravitational acceleration is about -9.8 m/s/s, assuming positive y is upward displacement and negative y is downward displacement)
When A baseball is hit straight up at an initial velocity of 100 ms how long will it take to hit the ground?
The baseball will travel upwards until its velocity is zero and then fall back down again. The acceleration of the baseball is the constant acceleration due to gravity acting in a downwards direction. The time taken to fall back down will be the same as the time to climb, thus the total time is twice the climb time. Use Netwon's equations of motion and ignore air resistance, the time to the top of the climb is: v = u + at → t = v - u/a v = final velocity = 0 m/s at the top of the climb u = initial velocity = +100 m/s a = acceleration = -g m/s² t_top = 0 - (100 m/s) / (-g m/s²) = 100/g s → t_total = 2 × t_top = 2 × 100/g s = 200/g s ≈ 200/9.81 s ≈ 20.4 s
Is the total time of a ball thrown upwards is it equal to the total time of the downward velocity?
There's no such thing as "time of the downward velocity", but I think I get the sense of your question. If the effects of air resistance can be disregarded, then any object thrown upwards spends half of its time rising, and the identical amount of time falling back to the height of your hand when you let it go.
What is maximum velocity?
maximum velocity is the highest possibly speed an object can travel before the forces acting on it reach an equilibrium and it is no longer able to accelerate. For example a parachutist will fall and accelerate rapidly until the air resistance pushing upwards against her downward force becomes balanced and her speed is steady, its more commonly known as 'terminal velocity' not maximum.
What does vt mean in the vertical motion formula?
it means initial upwards height times time in seconds
When object moves upwards what is the velocity and acceleration?
When an object moves upwards, its velocity is directed upwards if it is moving in the same direction as the motion. The acceleration, due to gravity, is directed downwards towards the center of the Earth. If the object is moving upwards against gravity, its acceleration is directed downwards but is a negative value.
What is its velocity at the highest point of a ball vertically upwards?
At the highest point of a ball's vertical motion, its velocity is zero. This is because the ball briefly comes to a stop before falling back down due to gravity.
An object is thrown vertically upwards from the top of a tower of height 39.2 meters reach the ground in 4 secons Find the velocity with which it is thrown upwards?
The velocity with which the object is thrown upwards can be found using the equation v = u + at, where v is the final velocity (0 m/s at the top), u is the initial velocity, a is the acceleration due to gravity (-9.81 m/s^2), and t is the time taken to reach the ground (4 seconds). Rearranging the equation to solve for u, we have u = v - at. Plugging in the values, u = 0 - (-9.81 * 4) = 39.24 m/s. Therefore, the object is thrown upwards with a velocity of 39.24 m/s.
What is the velocity of object when it is thrown above?
The velocity of an object thrown upwards will gradually decrease due to the force of gravity acting against it. At the highest point of its trajectory, the velocity will momentarily be zero before starting to fall back down.
What makes a thrown upwards body to stop for some few seconds before desendeing down?
When a body is thrown upwards, it reaches its highest point where its velocity momentarily becomes zero before descending due to the gravitational force pulling it back down. This momentary stop at the highest point is due to the balance between the upward velocity from the initial throw and the downward pull of gravity.
When is velocity antiparallel to acceleration?
Velocity is antiparallel to acceleration when an object is moving in the opposite direction of the acceleration. This means that the object is slowing down due to the acceleration acting in the opposite direction to the object's motion.
How fast must an object be thrown up if it is to stay in the air for 5 seconds before hitting the ground again?
The object must be thrown up at a speed of approximately 49 meters per second (98 m/s total velocity) to stay in the air for 5 seconds before hitting the ground again, assuming no air resistance. This calculation is based on the constant acceleration due to gravity of 9.8 m/sĀ².
How do you write the word bound in Chinese?
* the line or plane indicating the limit or extent of something * a light, self-propelled movement upwards or forwards
When tossing a coin upwards what happens to its velocity while ascending what happens to its acceleration?
As the coin is tossed upwards, its velocity decreases until it reaches its highest point where it momentarily stops before coming back down. The acceleration due to gravity is acting against the coin's motion, causing it to decelerate while ascending.
Definition for positive acceleration?
Positive acceleration occurs when an object is speeding up in the positive direction, meaning its velocity is increasing over time. This could be due to a force pushing the object in the positive direction, resulting in a positive rate of change of velocity.
Question-1 A body is thrown vertically upwards The distance st above the ground after t seconds is given by st 20t-5t2 meters?
The equation for vertical motion is y = v0t + .5at2. y is vertical displacement v0 is initial vertical velocity a is acceleration (in meters, normal gravitational acceleration is about -9.8 m/s/s, assuming positive y is upward displacement and negative y is downward displacement)
