What is the velocity of an object thrown vertically upward at the maximum height?

Therefore, at maximum altitude the velocity of the ball must be zero. Question: A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is: Answer: 0 m/s.

Why does the velocity of an object thrown vertically upward decreases as it goes up?

This is true even when an object is thrown upward or has zero velocity. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.

When a ball is thrown vertically upward its velocity goes on decreasing?

When a ball is thrown vertically upwards, its velocity goes on decreasing. As the velocity of the ball goes decreasing, its kinetic energy also goes decreasing and its potential energy starts increasing. And when the velocity becomes zero, its kinetic energy is zero and converted into its potential energy.

When a ball is thrown vertically upwards its momentum?

Momentum = Mass × Velocity Hence, momentum is zero.

What is the initial velocity of the ball thrown vertically upwards?

A ball is thrown vertically upwards with a velocity of 49 m/s. Calculate (1) The maximum height to which it rises. (2) The total time it takes to return to the surface of the earth. Initial velocity of the ball (u) = 49m/s.

What happens to the velocity of an object as it rises?

The object slows down as it moves upward until it reaches a maximum height, at which time the velocity is zero. Then the velocity increases as the object falls toward the ground. Note: If the initial velocity is great enough, the object may escape the force of gravity.

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.

What is the velocity with respect to time and gravity?

The general gravity equation for the velocity with respect to time is: v is the vertical velocity in meters/second (m/s) or feet/second (ft/s) g is the acceleration due to gravity (9.8 m/s² or 32 ft/s²) vi is the upward initial vertical velocity in m/s or ft/s (See Derivation of Velocity-Time Gravity Equations for more information.)
