Kinematics question -- Rocket launch
Homework Statement
A rocket starts from rest and moves upward from the surface of the earth. For the first 10s of its motion, the vertical acceleration of the rocket is given by ay=(2.70m/s3)t, where the +y-direction is upward.
A.What is the height of the...
kinematics question -- An automobile accelerating and braking
Homework Statement
According to recent test data, an automobile travels 0.250 mi in 19.9 s, starting from rest. The same car, when braking from 60.0 mi/h on dry pavement, stops in 146 ft. Assume constant acceleration in each part...
Cos of theta equals the x- coordinate. I realize that I got it wrong, but can you explain to me where i went wrong and how the homework came to that answer?
Why should it be negative? I understand that there are certain trig functions that are (+) and (-) in certain quadrants, but why is the the whole function negative?
I used the Pythagorean theorem to find the (square root) 6/7 but it should be negative because of the fact that it is the third quadrant. What I don't understand is how to determine whether the whole function is (+) or (-). Can you help me?
Homework Statement
Use the figure to evaluate the function that f(x)=sin(x)
f(θ/2)

The Attempt at a Solution
x2+y2=1
x= -2/7
(-2/7)2+y2=1
y=√(6)/7
sin(θ/2)= +/- √(1-cos(θ)/2) (the whole function is over 2 inside of the square root)
=+/-...
