Given the data in the question; Part a how fast would the car need to go to double its kinetic energy? V(new) 2 = 2 x v(old) 2 v(new) = (2 x 15 2) 1/2 v(new) = 450 1/2 which is approx.

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.

How fast would the car need to go to double its kinetic energy? For the car to be able to double its kinetic energy, it would need to travel at a speed of approximately 21.21m/s. A car is travelling at 10 m/s.

And So It Has A Kinetic Energy Off A Half M Times V.

By what factor does the car's kinetic energy increase if its speed is doubled to 20m/s ? How fast would the car need to go to double its kinetic energy? A car is traveling at 10 m/s.

For The Kinetic Energy To Become Double

Where m is the mass and v is the velocity. Two cars a and b are moving on a straight road. If the velocity of the car is decreased by half.

Let Velocity Be V, Then New Velocity Will Be 2V.

By what factor does the car’s kinetic energy increase if its speed is doubled to 20 m/s? We can conclude that kinetic energy depends quadratically on the object’s (the car’s) speed. Considering that the speed of the car with mass m was v so, its initial kinetic energy was = k.e =1/2 mv^2 now, if we double the speed, new speed will be v'=2v so, new kinetic energy will be k.e1=1/2 mv'^2 =1/2 m(2v)^2 =1/2 m 4v^2.
