If a ball is rolled off a ramp how do you tell how far it will go before it hits the floor?
say ramp angle = 30deg from horizontal, launch velocity = 10 m/s, launch point is 1m above floor
break launch velocity vector into horizontal and vertical components
horizontal = cos 30 * 10 = 8.66 m/s, vertical = sin 30 * 10 = 0.5*10=5 m/s
the horizontal component is constant so if you multiply the time the ball spends going up and down by 8.66 this represents horizontal travel
take g as -10 m/s^2, u=5, v=0 ,s=?, t=?
find height reached and time taken, t=v-u/g = 0.5secs, s=(u*t)+((g*t^2)/2)=1.25m, now add how long to fall 1.25 m+ original height (1m) = 2.25m
remember g is now +10 m/s^2, u=0, s=2.25m ,t=?
then t= sq root(s*2/10)=0.671secs(falling), add to 0.5 secs(rising) = 1.171secs, multiply by 8.66m/s then horizontal travel = 10.14 metres

What newtons law explains why a ball bounces?
when a ball is dropped it hits the floor and the ball is flattened. That creates energy. The only way the ball can release the energy is bouncing back up. But the ball starts to lose its height and the ball eventually loses its energy and comes to a stop.
What makes a ball bounce higher?
A ball bounces because it's shape changes when it hits another object, then it returns to it's original form, pushing itself away from the object. When a ball is cold it's molecules don't move as much, so the shape changes less when it hits an object.
How is tennis related to newton third law of motion?
newton's laws of motion apply to tennis because of the 3 law of motion. For every action there is an equal and opposite reaction. So when the ball hits the racket the force from the racket makes the ball move forward.Also the second law applies because the law is an object in motion will tend to stay in motion until an outside force acts upon it. So when the player hits the ball gravity is putting a force on the ball which brings the ball to the ground. If gravity didn't exist then the ball would go on forever.
Can wind or pressure from a cannon ball kill you?
A classical cannon ball doesnt have enough speed, but a modern heavy artillery shell will cause enough wind to blow bystanders away, and thus possibly kill them.
When an object falls from a height and bounces it's energy changes form When a ball bounces it's potential and kinetic energies change Eventually the ball will stop bouncing Why does the ball stop?
The ball stops bouncing due to a loss of energy through various forms such as heat, sound, and deformation of the ball. As the ball bounces repeatedly, these energy losses accumulate, causing the ball to eventually come to a stop.
Does the bowling ball have to cross the foulline before it hits the floor to be legal?
No.
When do you score in volley ball?
When the ball hits the floor of your opponents side of the court.
Can you hit the front wall and back wall in racquetball?
Yes, they are required to hit the ball before it hits the floor a second time ... no matter how may walls it hits.
If batted ball hits a base before it hits the ground is it an out?
No, it is simply a ground ball and is in play.
What are two forces that act when a ball hits a floor?
i think its compression and ... sorry i don't know the other one
When does your team score in volleyball?
When serving team hits the ball and returning team cannot return in three tries or when ball hits the floor. Serving team hits the ball and it goes out of bounds point for other side.
When a player serves the ball inside the court and it hits the floor without anyone touching the ball this is called?
It is called an Ace.
If you are trying to save the ball from going out of bounds and you throw the ball off of an opponent when he is out of bounds whose ball is it?
If the opponent has established position out of bounds (at least one foot on the floor) then the ball would still be yours. If the opponent is in the air and has not established position out of bounds the ball is still live.
What does the referee in volleyball game mean when he points his finger towards the floor?
This call is used when the ball hits the floor on one side of the court, so the referee points it at the floor, signifying the ball landed on that side and was in bounds.
When a player serves the ball inside the court and it hits the floor without anyone touching the ball wthis is it called?
This is called an ace.
What do you call the foot in netball that hits the floor when the player has the ball?
Landing foot? Or grounded foot.
What happens if the volleyball goes over but hits the floor?
