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.
48 metres 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.
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 speed of the ball is ( \frac{120 \text{ cm}}{15 \text{ sec}} = 8 \text{ cm/sec} )
what is the average speed of a soccer ball that travels 34 m in 2 s
To toss a ball straight up so that it takes 4.0 seconds to return to you, it must be thrown at a speed of 19.6 meters per second. This is because it will have a speed of zero at 2.0 seconds, therefore it must have a speed of 19.6 meters per second for gravity's 9.8 meters per second squared to slow it to zero in 2 seconds.
