Please help asap. A soccer player can kick a 0.370 kg football at 55 km/h. If the soccer player accidentally kicks the ball straight upwards and all of the kinetic energy turned into potential energy at the top of its path, how high would it go?

Which transition by an electron will release the greatest amount of energy? oa ob oc od

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
