Steps/Formulas Please! A ball is launched up a semicircular chute with radius 0.57 m in such a way that at the top of the chute, just before it leaves, the ball has a radial acceleration of magnitude 12.4 m/s^2.

How far from the bottom of the chute does the ball land?

Acharge of 8.4x10^-4 c moves at an angle of 35 degrees to a magnetic field that has a field strength of 6.7x10^-3 t. if the magnetic force is 3.5 x10 ^-2 n, how fast is the charge moving?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
