Question

Halliday, Fundamentals of Physics, 11e UNIVERSITY PHYSICS I (PHY 107) BACK NEXT A particle's position is given by x 18.0 15.00t+3, in which x is in meters and t is in seconds. (a) What is its velocity at r 1 s7 (b) ts it moving in the positive or negative direction of x just then? (c) What is its speed just then? (d) Is the speed increasing or decreasing just then? (Try answering the next two questions without further calculation.) (e) Is there ever an instant when the velocity is zero? If so, give the time t; if not, answer "O(t) is there a time after t3 s when the particle is moving in the negative direction of x? If so, give the time t; if not, answer "O m/s (e) Number[g m/s UnitsT s (e) Number 2 gen.Sbo.work || Click if you would like to show work for this questioni 虹 LINK TO SAHPLE PROBLEM INK TO TEXT LINK TO SAMPLE Pneu MATH HEL ATH HELP
