This question is all about the change in kinetic energy. Work is defined as the change in potential energy, but in this case, we can apply this to kinetic energy. Kinetic energy is defined as 1/2mv2. If we take the final kinetic energy, and subtract it from the initial kinetic energy, we will have work. In this case, 30000J-7500J=22500J Hope this helps!

Water. Water combined with sea salt will increase the speed of the nail rusting.
it would take 28 hours and 31 minutes give or take falling at an average speed of 140mph.

Work done = increase in kinetic energy ie 1/2 * 10 * (3+2)(3-2) [recall a2 - b2 = (a+b)(a-b)] Hence work done = 25 joule.
375 Js (((((((((((: this is the right answer

ti can only be done by using hacking tools. there is no way to increase th speed of working in good game farmer.
The work done on the snowboard can be calculated using the work-energy theorem. The work done is equal to the change in kinetic energy of the snowboard. Given the mass of 5kg and initial and final speeds of 2m/s and 4m/s respectively, the work done on the snowboard is 100 Joules.
The work done on the snowboard is calculated as the change in kinetic energy. The formula for kinetic energy is KE = 0.5 * mass * velocity^2. By calculating the initial and final kinetic energies, the work done would be the difference between the two. In this case, the work done on the snowboard is 60J.
The work done on the sled can be calculated using the work-energy principle. The change in kinetic energy of the sled is equal to the work done. Therefore, the work done on the sled would be the change in kinetic energy, which is calculated as (1/2) * m * (vf^2 - vi^2), where m is the mass of the sled (5g = 0.005 kg), vf is the final velocity (15 m/s), and vi is the initial velocity (10 m/s).

The speed at which work is done is called the work rate. It is measured as the amount of work completed in a given amount of time, typically expressed as units of work per unit of time (e.g. miles per hour, tasks per hour). A higher work rate indicates that work is being done more quickly.
