Answer:
A. 4.47 m/s
Explanation:
As the ball oscillates, it mechanical energy, aka the total kinetic and elastics energy stays the same. For the ball to be at maximum speed, its elastic energy i 0 and vice versa. When the ball is at rest, its kinetic energy is 0 and its elastic energy is at maximum at 50 cm, or 0.5 m
1500 g = 1.5 kg
It will take the quarter 0.151 seconds to reach the ground.
<u>Given the following data:</u>
- Height = 1.45 meters
- Initial velocity = 10.32 m/s
We know that acceleration due to gravity (a) for an object is equal to 9.8 meter per seconds square.
To find how much time it will take the quarter to reach the ground, we would use the second equation of motion.
Mathematically, the second equation of motion is given by the formula;
Where:
- S is the height or distance covered.
- u is the initial velocity.
- a is the acceleration.
- t is the time measured in seconds.
Substituting the values into the formula, we have;
The standard form of a quadratic equation is:
a = 4.9, b = 10.32 and c = 1.45
We would solve the above quadratic equation by using the quadratic equation formula;
Substituting the values, we have;
<em>Time, t = 0.151 seconds.</em>
Therefore, it will take the quarter 0.151 seconds to reach the ground.
