Two forces upper fsubscript upper a baseline overscript right-arrow endscripts and upper fsubscript upper b baseline overscript right-arrow endscripts are applied to an object whose mass is 10.6 kg. the larger force is upper fsubscript upper a baseline overscript right-arrow endscripts. when both forces point due east, the object's acceleration has a magnitude of 0.554 m/s2. however, when upper fsubscript upper a baseline overscript right-arrow endscripts points due east and upper fsubscript upper b baseline overscript right-arrow endscripts points due west, the acceleration is 0.313 m/s2, due east. find (a) the magnitude of upper fsubscript upper a baseline overscript right-arrow endscripts and (b) the magnitude of upper fsubscript upper b baseline overscript right-arrow endscripts.

Ben(55 kg) is standing on very slippery ice when junior(25kg) bumps into him. junior was moving at a speed of 8m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision .

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

A2-kg bowling ball is 2.5 meters off the ground on a post when it falls. just before it reaches the ground, it is traveling 7 m/s. assuming that there is no air resistance, which statement is true?
