A heavy paddle moving with velocity v hits a light ball moving in the opposite direction with velocity 3v. Assuming that the collision is perfectly elastic, what is the final speed of the ball? (Note that the paddle is much more massive that the ball and think about what the collision looks like in the reference frame of the paddle).

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

Estimate the schwarzschild radius (in kilometers) for a mini-black hole formed when a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (assume that the your weight is 50 kg)

Listed below are the measured radiation absorption rates (in w/kg) corresponding to 11 cell phones. use the given data to construct a boxplot and identify the 5-number summary. 1.16 0.85 0.69 0.75 0.95 0.93 1.18 1.17 1.42 0.54 0.57 the 5-number summary is nothing, nothing, nothing, nothing, and nothing, all in w/kg. (use ascending order. type integers or decimals. do not round.)
