1) how fast would the car need to go to double its kinetic energy? Kinetic energy(ke) = 1/2 m v 2 the first part (1/2 m) doesn’t change, you need a new value for v such that. V(new) 2 = 2 x v(old) 2 v(new) = (2 x 15 2) 1/2 v(new) = 450 1/2 which is approx. = 21. 21 meters per second.

It is the ability of objects to attain or reach a particular position by use of a known amount of force. Kinetic energy is measured in calories per second. Therefore, if a car is moving at a speed of mach 0. 15 miles per hour, then it would require about 3200 calories per second to go from a stationary position to its maximum speed. This probably we're told that we have a car that is moving with some initial velocity, which is 10 m per second. And so it has a kinetic energy off a half m times v. 💬 👋 we’re always here.
