What is the velocity of the ball just before it hits the ground?

Conclusion: The magnitude of the velocity of the ball is 26.3 m/s for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward.

What was the time taken by the ball to reach its maximum height?

It takes about 88 seconds for the cannonball to reach its maximum height (ignoring air resistance). You have 176 seconds, or 2 minutes and 56 seconds, until the cannonball destroys the cannon that fired it.

What is the acceleration when a ball is thrown in the air?

When you throw a ball up in the air, its direction/velocity on the way up, although it rises up into the air, is actually downward. On its way up, its speed decreases, until it momentarily stops at the very top of the ball�s motion. Its acceleration is -9.8 m/s^2 at the very top.

When a ball is thrown vertically upwards the gravitational potential energy of the ball?

When a ball is thrown vertically upwards, the kinetic energy of the ball converted into potential energy of the ball. But the total energy of the ball remains constant during its motion. So option 1 is correct. It is because at the beginning the ball has high kinetic energy and no potential energy.

What is the displacement of the ball at its highest point?

At its highest point, the ball will have a positive displacement, and will have a zero displacement when it returns to its starting point. If the ball isn’t caught, but continues toward the Earth past its starting point, it will have a negative displacement.

What is the maximum height of a ball thrown vertically upwards?

or H= v1 2/2g (equation of maximum height) ………. (iv) Therefore if a ball is thrown vertically upwards with 98 m/s velocity, the maximum height reached by it would be = (98 x98 )/(2 x 9.8) meter = 490 meter.

What is the acceleration of the ball as it rises?

Since the ball rises for 2.5 s, the time to fall is 2.5 s. [hidden-answer a=”430807″]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. [/hidden-answer]

When a ball is thrown upward the equations of fall apply?

If a ball is thrown upward, the equations of free fall apply equally to its ascent as well as its descent.

What is the initial speed of a ball thrown straight up?

A ball is thrown straight upward with an initial speed V0. When it reaches the top of its flight at height h., a second ball is thrown straight upward with the same initial speed. Do the balls cros… A sky diver (of mass m) is freely falling down.
