Answer:
This is one of the hottest summers America has ever seen and Jeremiah Warren is taking advantage of the heat wave and doing a little cooking…in his car!
It was about 98 or 99 degrees in Texas, so Jeremiah thought he’d head outside to see if it was hot enough to actually cook food. He buttered up a frying pan on his dashboard and filled it with an egg, cookie dough, a hot dog and bacon (mmm…bacon!). He set up another frying pan on the sidewalk and a few hours later he came back for a mid-day snack.

Answer:
Explanation:
First of all, let's convert 2.0 rev into radians:
This means that the angular speed of the wheel is
The angle through which the wheel rotates in a time t is given by
And substituting t=1.0 s, we find
In an elastic collision momentum is conserved as well as the kinetic energy
Explanation:
In physics, there are two types of collisions:
- Elastic collision: in an elastic collision, the total momentum of the system is conserved, and the total kinetic energy of the system is conserved as well. This is because there are no internal frictions acting on the system, so the energy is conserved. An example of elastic collision is (approximately) that occurring between two billiard balls.
- Inelastic collision: in an inelastic collision, the total momentum of the system is conserved, while the total kinetic energy is not. In fact, due to the presence of internal frictions, part of the total energy is converted into thermal energy and sound during the collision, and therefore "wasted", so the final total kinetic energy is less than the initial one. An example of inelastic collision is the collision between two cars. The maximum amount of kinetic energy is lost when the two objects stick together after the collision; in this case, we talk about perfectly inelastic collision.
Therefore, the complete sentence is
In an elastic collision momentum is conserved as well as the kinetic energy
