At a race track, a car of mass 1150kg crashes into a concrete wall at a speed of 85m/s. A.) If the car comes to a stop when it hits the wall, what is the magnitude of the impulse applied to the car?
B.) The car crashes into the wall, stopping in 0.1 seconds. What force is applied to the car?

the answer is kevlar

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
