Speed equals Distance over Time. Distance = 35 metres, Time = 5 seconds. 35/5 = 7 metres per second or 7ms-1

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
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
Speed can't be measured in seconds.
speed = distance/time --> time = distance/speed = (30 m)/(50 m/s) = 0.6 seconds
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
To calculate the time it takes for the ball to travel 20 meters, we first convert the speed to m/s: 150 km/h = 41.67 m/s. Then, we use the formula: time = distance/speed. Therefore, the ball takes approximately 0.48 seconds to travel 20 meters.
