x=1/2at2 and
a=9.81m/s2 so
2.88m = 4.905t2
t = 0.77 s
v=at so
v= 7.5 m/s
momentum = mv = (m)kg* 7.5m/s = 7.5m
Now with a mass of m/2 having a momentum of 7.5m we have to double the velocity.
7.5m = 7.5(m/2)*2 = 15m
To get a velocity of 15m/s
15m/s = at so t= 1.53 s
distance is x=1/2at2
x=1/2at2 x= 11.48m
It depends on what percent it was dropped.
Einstein dropped out of school when he was 16 in Munich, Germany.
The sound moves in a second 340 metres. That is in 3.8 seconds 1292 metres. But because there is the way down to the ocean and back to the ears of the stone dropper, the distance must be half of it. The cliff is 646 metres high.
Acceleration = (change in speed) divided by (time for the change)= (4.9) / 3 = 1.63 m/s2(rounded)
1050 is the four digit number don't know which mathematical procedure to use it took me 5 mins to make a small C# program and ta-da! that's it. :)) cheers
8.83 kg-m/s
Sure, if either of the following conditions is true: -- The smaller mass started dropping before the larger mass did. As long as (MsmallVsmall) is equal or greater than (MbigVbig), the smaller mass has equal or more momentum than the larger one has. But of course, the momentum of the larger mass catches up as its speed grows. -- The smaller mass and the larger mass were dropped at exactly the same time, but on different planets. Then, if the smaller one was dropped in a place where gravitation is greater, and the greater mass was dropped in a place where gravitation is less, it's quite possible for the smaller mass to have more momentum than the larger mass has, at least for a while. If the acceleration of gravity on the larger planet is at least (larger mass x acceleration of gravity on the smaller planet/smaller mass) or more, then the smaller mass has more momentum than the larger mass has forever, or as long as they're both freely falling.
Momentum. Momentum is the mass of an object multiplied by its velocity. This is expressed as: p=mv where p is the momentum, m is the mass, and v is the velocity. Also, kinetic energy, as that is 1/2 m*v^2.
Yes. In the formula P=mv, momentum, which governs the force of the impact, is equal to the mass of the object multiplied by the velocity. As the velocity increases, so does the momentum, therefore the greater the height dropped from, the greater the force of impact.
It has more momentum from a higher height. Because momentum is always conserved, and momentum is the product of mass times velocity, more sand particles must move away faster in order to conserve the momentum of a heavy ball moving fast. The ball is moving faster from a higher height because the acceleration due to gravity (-9.81 m/s^2) increases the velocity of a falling object after each second its been falling.
Ignoring air resistance (which probably is not safe to do) it would impact at a smidge over 18 seconds from when it was released and be traveling about 580 feet per second.
It really doesn't. What happens is that the bomb explodes on impact and the momentum causes the fluid to continue moving along the line of motion.
The knowledge of the process to create sparks, and thus start a fire, by striking two stones together is very ancient and was probably discovered by observation of the accident of one dropped stone striking another and throwing a spark. It was probably discovered at different times and in different places. The name of anyone who made that discovery a long lost in the mists of time.
12 did not break. (24 divided by 2 = 12)
No. The change in potential energy and momentum both depend on the mass of the object, and the metal ball and plastic ball have different masses. What's the same for both of them is their acceleration while they fall, the time they take to reach the ground, the moment when they hit the ground, and their speeds when they hit the ground.
mass x velocity = momentum
so 180 divided by 99 equals 0.55 then 0.55*100=55 as a percentage %55
