Graham, a physics enthusiast, is asked by his instructor to visit a nearby carpentry. He observed there a hand–held powered reciprocating saw, say a sabre saw, which performs SHM in a vertical plane with an angular frequency of 350 rad s−1 . Assume that the tip of the toothed blade of the saw is at x = 0 with positive velocity when t = 0 and the amplitude of SHM is 2.40 cm. Write an equation, as a function of time, which shows the position of the tip of the toothed blade. Also calculate that how much will the blade take to travel from x = 0 to x = 1.20 cm? To 2.40 cm?
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
