Best ResponseYou've already chosen the best response.0my question is: If the momentum of a moving object is increased by 100%. Than the Kinetic energy of that object will be increased by :

Best ResponseYou've already chosen the best response.0if we double momentum, that means instead of p = mv , we have p=2mv

Best ResponseYou've already chosen the best response.0KE = 1/2* mv^2 = 1/2* p* v

Best ResponseYou've already chosen the best response.0I think we can safely assume that all the in increase in momentum is due to velocity, not a change in mass

Best ResponseYou've already chosen the best response.0i guess kinetic energy would be doubled

Best ResponseYou've already chosen the best response.0so we essentially double our velocity

Best ResponseYou've already chosen the best response.0which quadruples our kinetic energy

Best ResponseYou've already chosen the best response.0we square velocity in the equation

Best ResponseYou've already chosen the best response.0bad explaination Kinetic energy of object mass m, velocity v: = (1/2) m v^2 Kinetic energy of object mass m , velocity 2v : = (1/2) m (2v)^2 = (1/2) m v^2 (4) = 4K
