A 0.55 kg basketball strikes a smooth floor at 4.0 m/s [20° below the horizontal] and rebounds at 4.0 m/s [20°above the horizontal].
a) Find the horizontal impulse acting on the ball.
b) Find the vertical impulse acting on the ball.
c) Is the collision elastic?
Treat a Boron atom as 5 protons at the origin, 2 electrons spread uniformly on a shell (radius 13.2[pm] centered on the origin) , 2 more electrons spread on a shell (radius 105.8[pm] centered on the origin), and its outer electron at x= 211.6 pm.
