1 A particle moves along a straight line. Its velocity vms
-1
Â at time ts is given by v t 2 0.6t
2 = .
Find an expression for the acceleration of the particle at time t. [2]
2 The height of the first part of a rollercoaster track is hm at a horizontal distance of xm from the
start. A student models this using the equation h x = 17 15 cos 6 , for 0 4 G Gx 0, using the values
of h given when their calculator is set to work in degrees.
(a) Find the height that the studentâ€™s model predicts when the horizontal distance from the start is
40m. [1]
(b) The student argues that the model predicts that the rollercoaster track will achieve a
maximum height of 32m more than once because the cosine function is periodic.
Â Comment on the validity of the studentâ€™s argument. [2]
