100 points. I need the answers PLEASE! (this is part of my test, and I have no idea what I am doing.) Will mark brainiest if you answer, this is one of my few questions. Bryan and Marc are two of my Ironman buddies and they have just had their fill at a local Subway and decide to do some Physics. Bryan has a mass of 85.0 kg with a pair of roller blades on. Marc pulls Ryan 5.00 m with a constant force and it takes him 7.66 s to accelerate Bryan from rest.

Calculate Average speed:

What was his initial speed (rest)? Vi

Calculate his final speed Vf. V=Vf+Vi

Calculate his acceleration.

Calculate the effective force Marc had on Bryan. F=ma

Apassenger walks toward the rear of a moving train. describe her motion as seen from a reference point on the train. then describe it from a reference point on the ground

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?

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
