Question 2 3 pts
If a car is traveling at 32 m/s and has a mass of 2,413, how much
Kinetic Energy does it have? (Round to the nearest tenth)

1235.5J

Explanation:

Given parameters:

Mass of car  = 2413kg

Speed of car  = 32m/s

Unknown:

Amount of kinetic energy it has  = ?

Solution:

Kinetic energy is the energy due to the motion of a body;

     Kinetic energy  = m v²  

m is the mass

v is the velocity

         Now insert the parameters;

     Kinetic energy  =   x 2413 x 32²   = 1235.5J

true tan speed = ang vel x radius

it has to be b, about 97 percent.
