: 1 Point Suppose That The Equation Of Motion For A Particle Where S Is In Meters And F In Seconds Is S 31 6t A 2 (37.63 KiB) Viewed 65 times

(1 point) Suppose that the equation of motion for a particle (where s is in meters and f in seconds) is s = 31³ - 6t (a) Find the velocity and acceleration as functions of t. Velocity at time t = Acceleration at time 1 = (b) Find the acceleration after 1 second. Acceleration after 1 second: (c) Find the acceleration at the instant when the velocity is 0. Acceleration:

f(x) = ln(3 + x²) (A) Use interval notation to indicate where f(x) is concave up. Note: When using interval notation in WeBWork, you use I for oo, -I for -∞o, and U for the union symbol. If there are no values that satisfy the required condition, then enter "0" without the quotation marks. Concave up: (B) Use interval notation to indicate where f(x) is concave down. Concave down: (C) Find all inflection points of f. If there are no inflection points, enter -1000. If there are more than one, enter them separated by commas. Inflection point(s) at x =
