Tag: How fast would the car need to go to double its kinetic energy?

A car is traveling at 15 m/s 1) How fast would the car need to go to double its kinetic energy? Kinetic Energy(KE) = 1/2 m V2 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 152)  1/2 V(new) = 4501/2…
