If the applied force changes to 520 n, what is the acceleration of the block up the ramp?
given mass = 46kg
angle of ramp = 50 degrees from horizontal
coefficient of friction = 0.38
original fa = 455.4

Suppose you were asked to find the torque about point p due to the normal force n in terms of given quantities. which method of finding the torque would be the easiest to use?

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?
