1.What is the force of a ball with a mass of 5 N if it accelerates
at 10 m/s/s?
2.What is the mass of a man if he
accelerates at 42 m/s/s and has
a force of 112N?
3.What is the acceleration of a
cat if it has a mass of 8 kg and
hits the cat flap with a force of
65 N?

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Aplane flying horizontally at an altitude of 1 mile and a speed of of 500mih passes directly over a radar station. find the rate at which the distance from the plane to the station is increasing when it is 2mi away from the station.

The energy equivalent of the rest mass of an electron is
