A mass attached to the end of a long spring is bouncing up and down. As it bounces, its distance from the floor varies sinusoidally with time. When the mass is released, it takes 0.2 s to reach a high point of 70 cm above the floor. It takes 2.6 s for the mass to reach the first low point of 32 cm above the floor. WW High point Low point 14. Write an equation which gives the height of the mass as a function of time. Your equation can have the formy = asin(b(x -c)) +dory =acos(b(x -c)) +d and should be in radians. Show your work in determining the values of a, b, c and d. Your answer 15. Use your equation to predict the height of the mass after 7 seconds. Round your answer to the nearest centimetre. Your
