The skater with a mass of 50 kg has a velocity of 20 m/s at the bottom of the ramp. How high vertically up the ramp will the skater be able to go? (Round off the acceleration of gravity to 10 m/s/s)
Your
1 m
10 m
20 m
30 m
40 m

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

conduction, convection, radiation

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
