Question

In Anchorage, collisions of a vehicle with a moose are so commonthat they are referred to with the abbreviation MVC. Suppose a1050 kg car slides into a stationary520 kg moose on a very slippery road,with the moose being thrown through the windshield (a common MVCresult).

(a) What percent of the original kinetic energyis lost in the collision to other forms of energy?
%

Answer 1

To calculate the percentage of the original kinetic energy lost in the collision, use the formulas for initial and final kinetic energy. Then calculate the difference and find the percentage.

Step-by-step explanation:

To calculate the percentage of the original kinetic energy lost in the collision, we need to find the initial and final kinetic energies and then calculate the difference.

The initial kinetic energy can be found using the formula:
Ki = 0.5 * m1 * v1^2 + 0.5 * m2 * v2^2

where m1 and v1 are the mass and velocity of the car, and m2 and v2 are the mass and velocity of the moose. The final kinetic energy can be calculated using the formula:
Kf = 0.5 * m1 * vf^2

The percentage of energy lost can then be calculated as:
Percentage lost = ((Ki - Kf) / Ki) * 100%
