If an object is projected upward with an initial velocity of 127 ft per? sec, its height h after t seconds is h equals negative 16 t squared plus 127 th=? 16t2+127t. find the height of the object after 55 seconds.

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Which is not one of the major climate zones? question 3 options: rain forest polar tropical temperate

An electron is traveling with initial kinetic energy k in a uniform electric field. the electron comes to rest momentarily after traveling a distance d. (a) what is the magnitude of the electric field
