59 g ball will travel upto 110 m/s
A. 110 m/s
<u>Explanation: </u>
Given datas are as follows
Speed of the pitched baseball = 45 meters/second
Mass of the baseball = 145 gram
Mass of the assumed ball = 59 gram
Both the balls travelled in the same momentum
Formula to find the momentum of an object is,
Momentum (p) = Mass (m) × velocity (v) (unit is kilogram meter per second (kg-m/s))
Momentum = 145 × 45 kilogram meter per second
Momentum = 6525 kilogram meter per second
Now calculate the speed of a ball with mass 59 g to have the momentum of about 6525 kilogram meter per second
Speed = momentum ÷ mass (meters per second)
Speed = 6525 ÷ 59 (meters per second)
Speed = 110 meters per second
Therefore a 59 gram (g) ball have to travel at a speed of 110 meters per second to have the momentum of 6525 kilogram-meter per second.
