HELP MATHS PROBLEM need really smart maths people
hey, got an assignment due VERY soon should have done it earlier was too busy riding.
can anybody please help me work this out.
The pilot of a small plane is attempting to land on a small airstrip, and the wheels hit the runway only 1000 metres short of a large group of trees at the end of the runway. The plane’s speed on the tarmac is modeled by the equation v = A-10^kt, where v the plane’s velocity in m/s, t is the time taken n seconds to come to a complete halt and A and K are constants.
*graph showing decelleration of plane*
If the pilot is attempting to land the plane at a speed of 80m/s,
a. Calculate the value of A (1 mark)
b. 8) investigate at least 3 different values of k between (but not including) 0.01 and 0.2 and for each value determine whether the plane comes to a complete stop before the end of the runway. Use any graphs and/or diagrams, any numerical techniques and any technology t
to support your arguments, justify your procedures. What physical conditions could make k vary? List assumptions you have made. Would there be any values of k (not just the values between 0.01 and 0.2) for which this equation could not be used to model the velocity of a plane landing on a tarmac? Give your reasons and justify your answer

Just put the new uni together in the driveway stopped to move the car and ran over the uni.
Felt like putting my head under the tire.
