∙ 12y agoWork 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.

Work done = Increase in kinetic energy SO W = (1/2) m (v22 - v12) So W = 12 x 5 x 3 = 180 J
When the bike is moving at 2 m/s, its kinetic energy is (1/2 m v2) = (5 x 4) = 20 joules.When it's moving at 3 m/s, its kinetic energy is (1/2 m v2) = (5 x 9) = 45 joules.The difference between initial KE and final KE is (45 - 20) = 25 joules.That's how much work you have to do on it in order to increase its KE.

The work done on the bicycle is equal to the change in kinetic energy. The change in kinetic energy is given by 1/2 * m * (vf^2 - vi^2), where m is the mass of the bicycle, vf is the final velocity, and vi is the initial velocity. Plugging in the values, the work done is 625 J.
To increase the speed of the car from 1 m/s to 2 m/s, you must apply a force using Newton's second law: Force = mass x acceleration. The force required will depend on the time over which you wish to achieve this acceleration, as accelerating too quickly may require a larger force.

To calculate the work done on the sled to increase its speed, you need to know the initial and final kinetic energy. The work done is equal to the change in kinetic energy, which is given by the formula: Work = (1/2) * m * (vf^2 - vi^2) Substitute the mass of the sled, initial speed, and final speed to find the work done.

The work done to increase the speed of the scooter can be calculated as the change in kinetic energy. The initial kinetic energy is given by (1/2)mv^2. The final kinetic energy is (1/2)m(20)^2. The work done is the difference between the final and initial kinetic energies.
The work done is equal to the change in kinetic energy, which can be calculated using the formula: W = ΔKE = 1/2 m (v_f^2 - v_i^2). Plugging in the values, the work done to increase the speed of the scooter from 10 m/s to 20 m/s is 6000 J.

The work done on the snowboard to increase its speed is 100 Joules. This work-energy theorem is based on the change in kinetic energy, given by the equation: work = change in kinetic energy. In this case, the snowboard has a mass of 10 kg and the speed increases from 2 m/s to 4 m/s.
