Answer:

Given :

Mass of car ==> 1000kg.

Change in velocity

==> Final velocity - Initial velocity = 20 - 5 ==> 15m/s.

To Find :

Kinetic energy of car ==> ?

By Formula

Kinetic energy of car ==> 1/2 mv²

==> 1/2 × (1000) × (15)²

==> 500 × 225

==> 112,500 joule.

Create a c program that determines how quickly an object is traveling when it hits the ground. The user will enter the height from which the object is dropped in meters (m). Because the object is dropped its initial speed is 0m/s. Assume that the acceleration due to gravity is 9.8m/s. You can use the formula vf =squareroot(vi+2ad)to compute the final speed, vf , when the initial speed, vi ,...
