Since the ball was not moving before it let Aiden's hand, the formula used to calculate the acceleration is
, where a is acceleration, v is velocity and t is the time. We put them in the formula and get
The acceleration is 490 m/s^2
Answer:
A
Explanation:
The acceleration of an object is directly proportional to its net force.
Answer:
Position A/Position E
, 
Position B/Position D
, 
, for 
Position C
, 
Explanation:
Let suppose that ball-Earth system represents a conservative system. By Principle of Energy Conservation, total energy (
) is the sum of gravitational potential energy (
) and translational kinetic energy (
), all measured in joules. In addition, gravitational potential energy is directly proportional to height (
) and translational kinetic energy is directly proportional to the square of velocity.
Besides, gravitational potential energy is increased at the expense of translational kinetric energy. Then, relative amounts at each position are described below:
Position A/Position E
,
Position B/Position D
, , for
Position C
,
