The largest land predator is the male polar bear, which typically has a mass of around 500 kg. If the maximum kinetic energy for a polar bear with this mass is 60,500 J, what is its top speed? need help asap

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?

The slope of a velocity time graph over any interval of time gives the during that interval

Me pl give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.
