Textbook QuestionA ball is attached to a horizontal cord of length ℓ whose other end is fixed, Fig. 8–45. (b) A peg is located a distance h directly below the point of attachment of the cord. If h = 0.80ℓ, what will be the speed of the ball when it reaches the top of its circular path about the peg?<IMAGE>30viewsHas a video solution.
Textbook QuestionThe small mass m sliding without friction along the looped track shown in Fig. 8–47 is to remain on the track at all times, even at the very top of the loop of radius r. (a) In terms of the given quantities, determine the minimum release height h.<IMAGE>21viewsHas a video solution.
Textbook QuestionThe small mass m sliding without friction along the looped track shown in Fig. 8–47 is to remain on the track at all times, even at the very top of the loop of radius r.
