What happens when a ball is thrown vertically downwards?
A ball is thrown vertically downwards from a height of 20 m with an initial velocity υ0. It collides with the ground, loses 50 percent of its energy in collision and rebounds to the same height. The initial velocity υ0 is (Take g=10ms−2)
What does vertically downward mean?
Vertical downward motion is a motion that has a negative velocity value and a negative acceleration value because the direction of the object is downward. This type of motion as well as the motion of the object thrown upwards is described by a quadratic function with concavity downwards.
What is the velocity of a ball thrown downward?
The initial velocity of a ball in downward direction is v=20 m/s v = 20 m / s .
Can Vertical be downwards?
Vertically downwards direction is used in the sense where an object is moving downwards towards ground and is perpendicular to the ground.
Which direction is vertically upward?
Answer: vertical suggests a line or direction rising straight upward toward a zenith. the side of the cliff is almost vertical perpendicular may stress the straightness of a line making a right angle with any other line, not necessarily a horizontal one.
What is correct about a ball thrown vertically upward at its maximum height?
We know the value of g in SI is 9.8 m/second square. So just for example, if a ball is thrown vertically upwards with 98 m/s velocity, then to reach the maximum height it will take = 98/9.8 =10 seconds.
What is the initial velocity of an object thrown downward?
If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s.
What direction is vertically?
The terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line goes across. You can remember which direction is vertical by the letter, “v,” which points down.
What is a jumping vertical?
A vertical jump or vertical leap is the act of jumping upwards into the air. It can be an exercise for building both endurance and strength, and is also a standard test for measuring athletic performance. It may also be referred to as a Sargent jump, named for Dudley Allen Sargent.
