While skiing in jackson, wyoming, your friend ben (of mass 69.8 kg) started his descent down the bunny run, 16.8 m above the bottom of the run. if he started at rest and converted all of his gravitational potential energy into kinetic energy, what is ben’s kinetic energy at the bottom of the bunny run? use g = 9.8 m/s 2 answer in units of j.

11484.18 J

Explanation:

Applying conservation of energy we get

potential energy = kinetic energy

mgh = 0.5mv^2

gh= 0.5v^2

h= 16.8 m

g= 9.8 m/s^2

v=18.14 m/s at the bottom of the bunny run

therefore, Kinetic energy at the bottom of the bunny run

K=

therefore K= 11484.18 J

= 11.48 KJ

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
