*When you throw a marble and a ping-pong bal at the same force,would it have the same distance??why???
*When you join a stopdance, why is it hard to stop even when the music stops?
THIS ARE ALL RELATED TO SCIENCE...
ANSWER THIS PLEASE..ITS REALLY URGENT

no they would not have the same distance due to air friction and the aero dynamics of each object. The smaller heavier object will be less effected by air friction and would probably go further assuming that you threw both objects from the same position with angle of departure.
I have no idea what a stopdance is.

Marble
wind resistance on ping pong ball slows it like a parachute.
density of marble bumps up the relative mass
force = mass x acceleration
acceleration is equal
mass of greater = greater force
in simpler terms, a marble fired from a slingshot will go over 50 yards easily, a pingpong ball would be lucky to go 20 yds

The marble ping pong ball thing. The marble would go further. It's relative to the mass of the object you are throwing. In this particular case it would be important that the objects both be round to, a square marble wont go as far as a round ping pong ball. Assume they are both round, the marble goes further. As for your second question, people are stupid so they don't respond quick enough. Just kidding. Ha..ha..ha..

1st question. The marble would go farther because the ping pong ball is light so it will lose force. The marble will go far since its heavier so it won't lose force and it will go far.
2nd question. Its really hard to stop when the music stops because when you dance, you're body really wants to do some more so if the music stops, its hard for you to stop.

About marble and ping pong ball
Assume any resistive force is neglected .
F=ma
Same force .
But the acceleration depends on their masses if they have the same mass , they would have the same acceleration.and would have the same distance .
S=1/2at^2+Ut
However if both of them have different masses the lighther one will cover a greater distance , as it will have the greater acceleration.
About the stop dance .
Its because of inertia . You r body resist changes in motion . same thing , when you press the brake of the car too hard , you move forward .(as body resist changes in motion , the body maintains it forward motion when the car is topping . so that's why you move forward )

the first answer is simple. The ping pong ball will bounce up the surface after hitting it but incase of marble it will come to rest, thus a ping pong ball will travel more distance.
When we dance our entire body has the the intria of motion so we have to apply some force & it takes sometime for us to come to rest.
BEST OF LUCK

1)Marble.
no ping pong ball weighs close to a marble
2) Inertia

1) it will only be the same distance if their masses are the same, otherwise is not....
2) bec of momemtum

They don't go the same distance and its hard to stop due to MOMENTUM.
