When an object is thrown vertically upwards what causes it to fall back to the ground *?

The cause of the ball’s acceleration is gravity. The entire time the ball is in the air, its acceleration is 9.8 m/s2 down provided this occurs on the surface of the Earth.

What is the acceleration when a ball is thrown upwards?

If you throw the ball upward with a speed of 9.8 m/s, the velocity has a magnitude of 9.8 m/s in the upward direction. Now the ball is under the influence of gravity, which, on the surface of the Earth, causes all free-falling objects to undergo a vertical acceleration of –9.8 m/s2.

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.

How does the ball return to the thrower in 8 seconds?

The ball returns to the thrower in 8 seconds. In these 8 seconds ball goes up against gravity and keeping going up till its velocity reduces to zero at the highest point. Thereafter the ball begins to drop towards the earth under gravity and reaches the point from which it was thrown up.

What is the maximum height of the ball after 4 s?

The maximum height reached by the ball (c). After 3 second, it starts to fall down. Hence after 4 s, the ball is at a height of 40 m above the ground. Was this answer helpful?

How long does it take for a ball to reach maximum height?

Look for spinal muscular atrophy symptoms. As mentioned, ball takes 4 seconds to come back to the same position. Therefore from this we can say it take 2 second to rise to maximum height and in next 2 second it falls from maximum height to the position where it is thrown (this is because time of accent = time of decent).
