Depending on the angle that the coins are falling, if they are falling heads down, completely horizontal with the ground, the quarter has more air resistance then the penny, making the penny hit the ground first. If they are on their sides, so the head is completely vertical with the ground, they are both arrow dynamic and the quarter and the penny hit at the same time. as the acceleration of gravity is -9.8 m/s squared, thus making they fall at the same acceleration.
A) the dropped one hits the ground first B) the tossed one hits harder
Sitting on the table the stone has potential energy, relative to the ground, of weight times height, mgh. It has zero kinetic energy so its total energy is E = 0 + mgh. When it begins falling it loses potential energy (as it loses height) and gains kinetic energy ( as it picks up speed) so the sum stays the same as initially E = KE + PE = mgh. Just before it hits the ground all of its potential energy is gone and has been transformed into kinetic energy. So the kinetic energy at the bottom (1/2)mv^2 will equal the potential energy at the top.
its too light
It falls down. When it reaches a hard bottom it is likely to bounce whereas if it hits water it will sink.
It's when there's a hot day and the rain boils and converts to gas before it hits the ground....that's where humid days come from
The velocity of the penny when it hits the ground can be calculated using the formula: velocity = acceleration due to gravity x time taken to fall. The acceleration due to gravity is roughly 9.81 m/s^2. Therefore, the velocity of the penny when it hits the ground is 44.145 m/s.
If it hits the ground then hits the batter then yes. If it just hits the ground then no.
The velocity of the penny as it hits the ground can be calculated using the equation: velocity = distance/time. Assuming the penny falls vertically, if we take the distance it falls to be 9.8 m/s^2 x (4.5 s)^2 / 2 ≈ 99.22 meters and the time is 4.5 seconds, the velocity would be 99.22 meters / 4.5 seconds = 22.04 m/s.
A dime. It is smaller and doesn't fight so much air against it.(:
A penny dropped from the top of a skyscraper would reach the ground in approximately 9.2 seconds. A passerby on the sidewalk below would have less than 9 seconds to move out of the way once they see the penny falling.
No, in that case it is a ball.

It is spotted at the point where the ball is when the knee hits the ground.
No. You fool.
In softball, if the batter is hit by a pitched ball after it has hit the ground, they are not awarded first base. The ball is considered a dead ball once it hits the ground, and the batter must avoid being hit by the ball. They are only awarded first base if the pitch is a strike and hits them directly without bouncing.
In regular baseball rules, the ball is still live, even if it hits the ground first, until it hits the batter, then it becomes a "dead ball". If it never hits the batter, its still a live ball.
In baseball, a ground out is an out in which a batter hits a ball on the ground and one of the Infielders catches it before it hits the ground and a ground out can also be an instance of a batter hitting a ball in which an Infielder fields a baseball and then throws to another Infielder in order to record an out as long as the batted baseball was hit on the ground.
