Studentl Ed Login- PleaseLA WaX law of Ohapredd www.webassign.net/web/Student/Assignment-Respo M Graphs of the velocity functions of two particles are shown, where t is measured in seconds. When is the particle in figure (a) speeding up? (Enter your answer using interval notation. When is the particle in figure (a) slowing down? (Enter your answer using interval notation 0 When is the particle in figure (b) speeding up? (Enter your answer using interval notation.) When is the particle in figure (b) slowing down? (Enter your answer using interval notation.
Explanation / Answer
acceleration is positive when velocity is increasing , negative when velocity is decreasing
speeds up when velocity and accceleration have same sign
slows down when velocity and accceleration have opposite sign
(a)
partical in figure (a) speeding up in (0,1),(2,3)
partical in figure (a) slowing down in (1,2)
(b)
partical in figure (b) speeding up in (1,2),(3,4)
partical in figure (b) slowing down in (0,1),(2,3)
please rate if helpful. please comment if you have any doubt
