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
re arange the equation speed=distance/time
Distance=Speed x Time
work out the speed of the ball and work out the time it takes to reach the end of the slope and then use that equation ^ to work out the answer (: x
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.
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.
You shouldn't go to your basement in a hurricane anyway. The main killer in a hurricane is flooding, not wind. Unlike tornadoes you will usually have a few days warning before a hurricane hits. This will give you time to board up your windows. Stay on the first floor of your home and be prepared to move higher if the first floor floods.
Yes.

No.
When the ball hits the floor of your opponents side of the court.
Egg's outer surface is rigid whereas the surface of basket ball is elastic in nature. So basket ball bounces but egg gets broken when they hit the floor.
Yes, they are required to hit the ball before it hits the floor a second time ... no matter how may walls it hits.
No, it is simply a ground ball and is in play.
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.
It is called an Ace.
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.
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.
This is called an ace.
The team that hit the ball over will get a point.
Landing foot? Or grounded foot.
