A weight is bouncing on a spring. It's height from the ground yaries sinusoidally with time. As the weight is bouncing, you start a stopwatch. You note that at t = 4 seconds, the weight is at a minimum height ofd cm off the ground. After another 1.2 seconds, the weight has gone from this minimum to its maximum height of 14 cm off the ground a} Write a function to model the height, in centimeters, of the weight as a function of t, the number of seconds since you started your timer b} Determine, to the nearest hundredth of a second, the second positive value oft for which the height ofthe weight is 13cm. No work necessary, and I will use whicheyer function you wrote in a to determine the correctness of your response
