Aball is thrown against a wall and bounces back toward the thrower with the same speed as it had before hitting the wall. does the velocity of the ball change in this process? a) although the speed is the same, the direction has changed. therefore, the velocity has changed. b) the velocity is the same because the speed is the same. c) without knowing the mass of the ball, the velocity is not determined. d) the velocity is now twice as large because the ball is going into the opposite direction.

Aforce of 34.5 newtons is applied to an object at an angle of 45 º with the horizontal. what is the force acting on the object in the horizontal direction?

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
