Write an equation for the height of the point P above the ground as a function of t, time in seconds. h(t) = Hint: Start by thinking: What is the height of the point P above the center? How is the center changing? Solution height of center at ant time = R + 7(sinA)t = 2 + 7(100/700)t = (2 + t) cm now height of P wrt center = Rcos(x/2) where x = 7t height of P = 2+ t + Rcos(7t/2) = 2 + t + 2cos(7t/2) 7t/2 is value in radian. oon putting t in second for t= 0,(starting point) height = 2 + 2cos0 = 4 cm at the end, at = 100 cm, h = 2 + 100 + 2cos(350) = 101.433 cm.
