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

9.81 meters/second/second
And the acceleration due to gravity is constant on the object thoughout its flight. So the acceleration of the projectile is equal to the acceleration due to gravity, 9.81 meters/second/second, from just after its thrown, through its highest point, and until just before it hits the ground.

When a ball reaches maximum height What is the acceleration?

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. The instantaneous speed of any projectile at its maximum height is zero….Objects Launched Upward.

Variable	Value
a	-9.8 m/s2
t	0.40 s

What is the height reached by the ball after 1 second?

After 1 second, the height of the ball is 86 feet.

How long does it take a ball to hit the ground?

A ball is dropped from 10.0m. How long does it take to hit the ground? This depends largely on the density of the object being dropped versus the medium in which it’s dropped and the gravitational acceleration at the location.

What is the acceleration of the ball when it drops?

Assuming there is no significant air resistance, the ball will have traveled y=0.5g (t^2) meters during time t from its drop. g is the gravitational acceleration on earth (g~9.8m/s^2). For y=10m, and solving for t; Seniors using loophole to save for retirement.

How do you find the direction of velocity of a ball?

If it is a two-dimensional problem – that is, the ball is tossed at an angle from some height, then one needs to know both the horizontal speed when it hits the ground (hint: same as the initial horizontal speed) and the vertical speed as it hits the ground. Those two components will yield the velocity – that is the speed and direction.
