A roller coaster car drops a maximum vertical distance of 35.4 m. Part A Determine the maximum speed of the car at the bottom of that drop. Ignore work done by friction. Express your answer with the appropriate units.

26.34 m/s.

Explanation:

Given:

h = 5.4 m

g = 9.81 m/s^2

Change in Potential energy = change in Kinetic energy

mgh = 1/2mv²

gh = 1/2 v²

v = √2gh

= √2×9.8×35.4

=√693.84

v = 26.34 m/s.

  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
