If the ball was dropped from a roof and hit the ground 3.03 seconds later, then when it hit the groundits velocity was 29.694 meters (97.42 feet) per second (rounded) downward.
The acceleration of gravity is 9.8 meters per second2 .In 3 seconds, gravity increases the falling speed by (9.8 x 3) = 29.4 meters per second.This particular ball already had a downward speed of 6 m/s when the 3 seconds began,so at the end of the 3 seconds, its velocity is(6) + (9.8 x 3) = 35.4 meters per second downward
The idea is to divide the distance by the time.
Average speed is calculated by dividing the total distance traveled by the total time taken. In this case, 32 meters divided by 0.8 seconds is 40 m/s. Therefore, the average speed of the bowling ball is 40 m/s.
The ball's speed is 9.4 meters per second.

Answer: 3 seconds
If the ball was dropped from a roof and hit the ground 3.03 seconds later, then when it hit the groundits velocity was 29.694 meters (97.42 feet) per second (rounded) downward.
The average speed is 16.66... (repeating) metres per second. It is not possible to calculate the average velocity without further information because, due to gravity, the velocity is changing continuously during the ball's flight.
Speed can't be measured in seconds.
The acceleration of gravity is 9.8 meters per second2 .In 3 seconds, gravity increases the falling speed by (9.8 x 3) = 29.4 meters per second.This particular ball already had a downward speed of 6 m/s when the 3 seconds began,so at the end of the 3 seconds, its velocity is(6) + (9.8 x 3) = 35.4 meters per second downward
The idea is to divide the distance by the time.
Average acceleration during a time interval = (change in speed) divided by (time for the change) =(25) / (5) = 5 meters per second2
