A 10kg bowling ball rolls off the table and strikes the ground if the ball is in the air for 8 seconds how fast is the ball moving when it hits the ground?

As is typical of this type of question, I am going to assume that the falling Bowling ball is not affected by the friction of the air through which it falls.
The formula for velocity is v = gt where g is acceleration due to gravity, 9.8m/sec2
After 8 seconds, the ball is falling at v = 9.8m/sec2 * 8 sec = 78.4 m/sec.
If it really has a mass of 10kg, it's not a bowling ball. Bowling balls are limited to about 7.27 kg.

You drop a 5 kilo ball from rest from a height of 20 meters how fast is it moving when it strikes the ground?
20 meters per second
If a bowling ball and a soccer ball are rolling along the ground at the same speed the bowling ball has more of this because its mass is greater?
The bowling ball has more momentum because momentum is directly proportional to an object's mass and velocity. Since the two balls are moving at the same speed, the greater mass of the bowling ball results in it having more momentum.
If a bowling ball is moving torwards the bowling pin which direction is the net force acting?
The net force would be in the direction of the bowling ball's motion, which in this case would be towards the bowling pin.
If a stone falls past a bird on a ledge moving at 4 meters per second how fast will the stone be moving just before it hits the ground below 9 seconds later?
92.2m/s
Rae dropped a bowling ball from a height of 8 meters. At which distance above the ground was the ball MOST likely moving at the greatest speed?
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.
How many moving parts are in a bowling machine?
The number of moving parts will vary depending on the make and model of the pinsetter.
What is the duration of Moving Wallpaper?

What is the duration of Moving Up?
The duration of Moving Up is 1440.0 seconds.

What are uses of friction?
Friction is used in various applications such as slowing down moving objects (brakes on vehicles), improving grip (shoes on the ground), holding objects together (screws), and in machines to transfer power (transmission systems).
Will a bowling ball or a golf ball hit the ground first from two rooms high?
If air resistance can be ignored (and it probably can from 2 rooms high) then both the bowling ball and golf ball will hit the floor at the same time. Although the bowling ball is harder to get moving than than the golf ball (it has more mass), the bowling ball also has a greater force pulling it down than the golf ball (as measured by its weight). The result is that both objects have the same acceleration.
How long did the twister stay on ground?
The duration of a tornado can vary greatly, from just a few seconds to several hours. The length of time a tornado stays on the ground depends on various factors such as the speed at which it is moving, the strength of the tornado, and the terrain it encounters.
