A solid ball with a mass of 4.25 kg and a radius of 0.026 m starts from rest at the top
of a 27.50 slope with a vertical height of 1.00
m. It proceeds to roll without slipping down
the slope.
What is the translational speed of the ball
when it reaches the bottom? The acceleration
of gravity is 9.81 m/s?.
Answer in units of m/s.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
