A ball is dropped from a certain height. What is its initial speed?
When a ball is dropped from a certain height, its initial speed is 0 m/s as it starts from rest. The ball gains speed as it falls due to gravity pulling it downwards.
A ball is dropped from a height of 100 cm At each bounce it raises half the height it raised with the previous bounce Find the distance covered by the ball till it comes to rest?
300cm. Ignoring the first drop, the first bounce is 50+50cm (up then down!), the second is 25+25, the third 12.5+12.5 ... and so on. If you know or accept that 1+1/2+1/4+1/8+1/16...=2 then the bounces add up to 100+50+25+12.5...=200, and then add the initial 100cm drop to make 300cm.
Why doesn't a bouncy ball bounce as high as from where it was dropped?
When a bouncy ball is dropped, it loses some of its energy to factors like air resistance and friction with the ground. This loss of energy reduces the height of the bounce compared to the initial drop height. The ball's elasticity also plays a role, as it absorbs some of the energy during the bounce.
How many meters will a 20kg ball starting from rest fall freely in one second?
9.8 meters if you are on the planet Earth. Weight does not matter.
When a ball is at rest all the forces acting on it are?
When a ball is at rest, the forces acting on it are balanced. This means that the force of gravity pulling the ball down is exactly counteracted by the normal force pushing up on the ball from the surface it rests on. As a result, the net force on the ball is zero, and it remains at rest.
If your golf ball is on the cart path and a drop is allowed how many times can you drop the ball?
You drop it once, if it comes to rest on the path, you drop it again, on the second drop if it comes to rest on the path you place it where the ball touched the grass first on the second drop.
You drop a 5 kilo ball from rest from a height of 20 meters how fast is it moving when it strikes the ground?
20 meters per second
If a ball is dropped from a height of 24 m and with each bounce the ball reaches a height that is half the height of the previous bounce how far has the ball traveled by the time it comes to rest?
72 meters
A ball is dropped from height of 24m. With each bounce the ball reaches a height that is half its previous bounce. How far has the ball traveled by the time it comes to rest?
72 meter
When your ball comes to rest in G.U.R. Are you entitled to a free drop and where?
yes, you go to the nearset point of relief then two clucb lengths no closer to the hole then drop the ball
Does the rebound height has a constant relationship with the original height of a tennis ball when released from rest and bounces on a bench?
As long as the tennis ball is not thrust downward, yes, the tennis ball will bounce back to the same proportion of its original height, no matter how far it's dropped, as long as the height is small enough that air resistance can be ignored. The ball will eventually come to rest due to this air resistance.
A ball of mass 0.150kg is dropped from rest from a height of 1.25m. it rebounds from the floor to reach a height of 0.960m what impulse was given to the ball by the floor?
1.39 Ns up
If the ball is next to a hole what is the time limit for it to drop in?
Once you hit the putt and the ball is at rest, you are allowed to walk to the hole and wait for only ten seconds. If by 10 the ball doesn't drop you must tap it in.
If a ball is dropped at a height of 24 meters with each bounce the ball reaches the height that is half the height of the previous bounce how far does the ball travel by the time it comes to rest?
Answer: 66 Meters. Just had that same problem on a math mates worksheet.
A ball is dropped from a certain height. What is its initial speed?
When a ball is dropped from a certain height, its initial speed is 0 m/s as it starts from rest. The ball gains speed as it falls due to gravity pulling it downwards.
Will a ball drop rest reach the ground quicker than the one lunched from the same height but with and initial horizontal velocity?
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
When you have to drop within two club lengths does this mean the ball must land within the two club lenghts?
Yes, you must drop the ball within the two club lengths and the ball must come to rest within the two club lengths.
