I need help setting this problem up. Please help! A mother pushes a stroller up a hill, with the center of the stroller 1 meter
ahead of her body. She maintains contact with the stroller at all times. Her position is x(t), speed is v(t) and her acceleration is a(t). What are the position, velocity, and acceleration of the stroller at any time t?
The only thing you can derive ...maybe ... from the given information is that the stroller's x(t) is 1 + the mother's x(t). And if her progress is not strictly along the x-axis, then even <em>that</em> statement isn't true.
If the stroller's v(t) and a(t) were not identical to the mother's v(t)and a(t), then mother and stroller would "come apart". But you've told us that they're always in contact, so their v(t) and a(t) must be identical.
A slightly more rigorous (and mathematical) argument is that since the mother's and the stroller's x(t) differ (at most) only by a constant, then their derivatives x'(t) (which is v(t)) and x''(t) (which is a(t)) are equal.
A^2 + b^2=c^2 that is how to find magnitude xcos0=20cos180 ycos0=20sin270 that should give you the vectors and your answer should state the quadrant degree which it is in and vector and direction it is in like west,south
He will not succeed as it blows the trumpet harder that only increase the amplitude of the sound wave that means the intensity of the sound will increase but the frequency remains the same.
