To find the velocity of the elevator, we need to use the equation for kinetic energy: KE = 0.5 * m * v^2, where KE is the energy (4000 J), m is the mass (5000 kg), and v is the velocity. Rearranging the equation to solve for velocity, we get v = sqrt((2 * KE) / m). Plugging in the values, we get v = sqrt((2 * 4000) / 5000) = sqrt(8/5) ≈ 1.26 m/s.

How much energy is required in changing the velocity of an object of mass 5000kg from 20ms to 30ms?
Initial kinetic energy = 1/2 M Vi2 Final kinetic energy = 1/2 M Vf2 Difference = 1/2 M (Vf2 - Vi2) = 2,500(302 - 202) = 2,500(900 - 400) = 2,500 x 500 = 1,250,000 joules

How much is 80 percent of 5000?
4000 Solution Method: 1. Convert 80% to decimal: 80 / 100 = .8 2 Compute answer: .8 * 5000 = 4000 Note: You could also obviously do it this way too: 80 / 100 * 5000 = .8 * 5000 = 4000 ============== Original Posters Answer: To calculate p% of a number, you need to multiply it by p and divide by 100, so 80% of 5000 is 5000 * (80 / 100) = 5000 * (4/5) = 4000
What is 5000 is 1000 more than?
Well, isn't that a happy little math problem! If you take 1000 away from 5000, you'll find that it leaves you with 4000. So, in a way, you could say that 5000 is 1000 more than 4000. Just remember, in the world of numbers, there's always a way to find balance and harmony.
What is the percent change from 4000 to 5000?
