The altitude of a specialized research probe, H(t)H(t)H(t) in kilometres, is modelled for time t>0.5 t > 0.5\,t>0.5 seconds using its vertical acceleration.
It is given that:
Determine the equation of the normal to the graph of altitude against time at the point PPP. Give your answer in the form at+bH+c=0at + bH + c = 0at+bH+c=0, where a,b, a, b,\,a,b, and c c\,c are integers.
Find an expression for H(t)H(t)H(t) in terms of ttt.
