Expert Solution

Introduction:

We are given a particle moving in 1 dimension which is x axis. We are given the velocity of particle as function of time. We have to tell how many turning points does the particle encounter. When the particle encounters turning point, its velocity becomes zero.

A particle moves so that its velocity (ms-') at time t seconds is given by the formula v = e2sin 31 cos3t. a Find: i an expression for the acceleration of the particle ii the time t at which the particle's acceleration is first equal to -0.5 ms-2. b Find an expression for the displacement of the particle (s) from its initial position at time t. c Write down the exact value of the maximum displacement of the particle.
The answer for this problem would be "C" but could you explain me why? The reason for this is to understand this kind of problems in the future not only this one.
a. What is the maximum speed in meters/second? b. At t = 1, the particle is (moving to the) (right/left/stopped) c. What time intervals is the particle's acceleration negative? < t < and < t < d. At t = 6, the particle is (moving to the) (right/left/stopped) e. At t = 1.5, the particle is (speeding up/slowing down) f. At t = 5.5, the particle is (speeding up/slowing down)
