48 metres per second.
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
speed = distance/time --> time = distance/speed = (30 m)/(50 m/s) = 0.6 seconds

Depends on the speed the ball travels.
The ball's speed is 9.4 meters per second.
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.

Answer: 3 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 speed of the ball is ( \frac{120 \text{ cm}}{15 \text{ sec}} = 8 \text{ cm/sec} )
Speed can't be measured in seconds.
First, determine the height the ball travels using the equation h = (1/2)gt^2, where h is the height, g is the acceleration due to gravity, and t is the time. Since it takes 4 seconds to return to you, the total time for the round trip is 8 seconds (4 seconds up and 4 seconds down). Then, set the height when the ball is released to the height when it returns. Finally, solve for the initial velocity needed to achieve this height in 4 seconds.
