∙ 15y agoThis 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!

How much work must be done on a 10kg bicycle to increase its speed from 2 M's to 3 M's?
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.
