Answer #1

4) f() is the position of the fourtiele, moving along X - anis, at the time t. Given : X 20. f(3) = -3 and f(2) - 6 So, posi6 at $(d) is the noise level (in decibals) of nock concert a distance & meters from the concent speakers. So, f(70) is the noIn (5), as there is no supplied accelaration, we have to assume constant velocity motion of the particle.
