A body like that shown in Fig. 14.2 oscillates back and forth. For each of the following values of the body’s x-velocity vx and x-acceleration ax, state whether its displacement x is positive, negative, or zero. (a) vx > 0 and ax > 0; (b) vx > 0 and ax < 0; (c) vx < 0 and ax > 0; (d) vx < 0 and ax < 0; (e) vx = 0 and ax < 0; (f) vx > 0 and ax = 0.

- What positive value of x/A gives v= 0.56 v_max, where A is the amplitude of the motion?arrow_forward5.arrow_forwardThe velocity of a particle performing S.H.M. is 3n cm/s when its displacement is V 12 cm. If the maximum acceleration of the particle is 9n ? cm/s?, find the frequency and amplitude of its oscillations.arrow_forward

Determine (a) when the velocity is zero, (b) the posi- tion and the total distance traveled when the acceleration is zero.arrow_forward11.14arrow_forwardA vinyl record is played by rotating the record so that an approximately circular groove in the vinyl slides under a stylus. Bumps in the groove run into the stylus, causing it to oscillate. The equipment converts those oscillations to electrical signals and then to sound. Suppose that a record turns at the rate of 33 rev/min, the groove being played is at a radius of 13.5 cm, and the bumps in the groove are uniformly separated by 0.136 mm. At what rate (hits per second) do the bumps hit the stylus?arrow_forward

(c) You then walk 4 steps in the negative x direction. (d) You then walk 5 steps in the positive x direction. Document (11) 1. Write the displacement for each part of the motion Axa = Axb= Axc= Axd= 2. Show the addition of the 4 displacement vectors in a diagram below. Draw the vectors tip to tail. Then connect the tail of the first vector to the tip of the last vector to get the resultant vector. 3. What is the magnitude of the resultant vector (i.e., what do you get when you add all 4 displacements together)? 4. How far away from the origin do you end up? Part B: Vectors in Two Dimensions 1. You walk from the origin 11 steps East, then turn and walk 9 steps North. a. How far from the origin do you end up? a b.
