    terminal velocity (M1)

    A skydiver of mass m kg steps out of an aircraft and starts to fall. The air resistance when his speed is v ms^-1 is given by kv^2 newtons. If his terminal speed is 40 ms^-1, find an expression for k in terms of m. (I did this part, got (m/160), which is correct) When his speed reaches 16 ms^-1...

    If (a,b) is a point on the terminal side of angle t in standard position, then cos(t)

    How do I know what it is supposed to be? Please explain. Thank you!

    Graphing with terminal velocity

    My notes didn't show how the second derivative was evalated. Would I need to plug in the same values I used in the first derivative inside the second derivative to figure out whether v'' is greater than or equal to zero?

    If sin θ < 0 and cos θ > 0, then the terminal point determined by θ is in:

    If sin θ < 0 and cos θ > 0, then the terminal point determined by θ is in: A. quadrant 2 B. quadrant 1 C. quadrant 3 D. quadrant 4 For some reason I am thinking its D. quadrant 4? (because It's the quadrant where y < 0 and x > 0, which is quadrant 4.) is this right? Please...

    determining the values of the primary and reciprocal ratio on a point on terminal arm

    The point is (3, -4) So I drew the point and the line. The Cos ratio should be positive since it's in the 4th quadrant. I can't quite figure out what do at after drawing the terminal arm. Any tips would be appreciated.

    terminal side

    Hello. I am having difficulty with this problem: Find the point on the terminal side of θ = ​-3pi/4 that has an x coordinate of -1 I was hoping that someone here would be able to help me out? I am actually trying to figure out what I am doing so if you could explain how you found the answer, I...

    Terminal Arm Location

    You are given Cos(theta) = -(5/13) .0<theta<2pi In which quadrant(s) can the terminal arm be,. I believe quadrants 2 and 4 but the back of the book is saying 2, and 3 (Angry) I think it is 2 and 4 because the points of its location could be (-5, 13) Q2 or (5, -13) Q4 If i am wrong...

    Terminal speed

    A racing car of mass m travels along a straight road. While travelling, the car is subject to a constant frictional resistance force of magnitude a*m (a, a positive constant) and an air resistance force of magnitude k*(v^2), where v is its speed. The car engine can provide a constant propelling...

    terminal velocity

    A parachutist whose mass is 100kg drops from rest to an altitude of 3000m and falls under of gravity. Assume that the force due to to air resistance is proportional to the velocity of the parachutist , with the proportionality constant k1 = 20kg/s when the chute is closed and k2=100 kg/s when...
