A ball swings counterclockwise in a vertical circle at the end of a rope 1.59 m long. When the ball is 37.30 past the lowest point on its way up, its total acceleration is (—16.57 + 21.6j) m/s . For that instant, do the following. (a) Sketch a vector diagram showing the components of its acceleration. Choose File No file chosen This answer has not been graded yet. (b) Determine the magnitude of its radial acceleration. m/s2 (c) Determine the velocity of the ball. m/s magnitude direction 0 counterclockwise from the +7 direction stuck on this question Title: Re: Physics question Post by: hule4 on Oct 11, 2023 (https://biology-forums.com/gallery/qpics/6_11_10_23_9_23_48.png)
See the sample problem attached a) (https://biology-forums.com/gallery/qpics/6_11_10_23_9_21_44.png) b) (https://biology-forums.com/gallery/qpics/6_11_10_23_9_21_54.png) c) (https://biology-forums.com/gallery/qpics/6_11_10_23_9_22_15.png) (https://biology-forums.com/gallery/qpics/6_11_10_23_9_22_28.png) (https://biology-forums.com/gallery/qpics/6_11_10_23_9_22_42.png) Title: Re: Physics question Post by: s.h_math on Oct 12, 2023 in this case wouldnt the ans for a for my question be b from the solution you provided?

Title: Re: Physics question Post by: bio_man on Oct 12, 2023 They're nearly identical, aren't they? One is drawn by hand, the other is illustrated
Title: Re: Physics question Post by: s.h_math on Oct 13, 2023 sounds good
