When a ball is thrown vertically upwards it goes through a distance of 19.6 m find the initial velocity of the ball and the time taken by it to rise to the highest point?

Thus the acceleration in the ball is negative which means that the value of g is to used here with the neagtive sign. Thus ,the intial velocity of the ball is 19.6 m/s which means that the ball has been thrown upwards with a velocity of 19.6 m/s .

What is the maximum height of a ball thrown upward?

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….Objects Launched Upward.

When a ball is thrown vertically upwards What is the velocity?

49 m/s.
A ball is thrown vertically upwards with a velocity of 49 m/s. (i) The maximum height to which it rises, (ii) The total time it takes to return to the surface of the earth. Acceleration due to earth gravity g = -9.8 m/s^2 (thus negative as ball is thrown up).

When we throw a ball upward initial velocity?

(t) Since, the ball is moving under the effect of gravity, the direction of acceleration due to gravity is always vertically downwards.

When a ball is thrown vertically upwards why does its velocity decrease?

Work is done only when the force applied to a body moves through a distance. When the ball is thrown vertically upwards, its velocity decreases, and its kinetic energy also decreases.

What is the initial velocity of an object thrown upward?

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. If an object is projected upwards in a perfectly vertical direction, then it will slow down as it rises upward.

What happens when a ball is thrown upwards?

When the body is thrown upwards, it moves up until the velocity of the ball becomes zero and the force exerted on it becomes zero. After that the ball reaches the ground with the acceleration due to gravity with the zero velocity. When the ball goes up, the height of the ball increases and it also moves up.

When a ball is thrown upwards with an initial velocity what will be its acceleration?

The acceleration is 9.8 m/s2 everywhere, even when the velocity is zero at the top of the path. Although the velocity is zero at the top, it is changing at the rate of 9.8 m/s2 downward.

When a ball is thrown vertically upwards then?

When a ball thrown vertically upwards it’s velocity is zero but acceleration is non-zero. Acceleration will be equal to ‘g’.
