Y(t)

from class:

AP Calculus AB/BC

Definition

In calculus, y(t) represents the position of an object along the y-axis at a given time t. It is often used to describe the vertical motion of an object.

congrats on reading the definition of y(t). now let's actually learn it.

ok, let's learn stuff

t seconds after a Calculus textbook is dropped from a building, the rate of change of the textbook’s position is proportional to the amount of time passed. If y(t) is the position of the textbook at time t, which of the following differential equations represents this situation?
Greg is bowling with his friends and rolls the ball at time t = 0. Consider the center axis of the lane to correspond to line x = 0 and the pin deck to be at the line y = 15. The gutters correspond to the lines x = -4 and x = 4. If a ball falls into a gutter before hitting any pins, Greg’s score is 0. The motion of the ball can be described by the parametric functions y(t) = -4t^2 + 16t and x(t) = -2t. Will Greg’s bowling ball reach the pins before the gutters?
The motion of a rolling ball on the coordinate plane is given by the set of parametric equations x(t) = 12sin(t) and y(t) = 6t^2. Which of the following derivatives is incorrect?
A particle moves on the xy-plane. The following equations about the particle’s movement are true: dy/dx = 4t^2 - 1 and dx/dt = t. Find y(t) given that y(0) is 25.
You shoot a ball horizontally off the edge of a chair. You observe that the vertical position of the ball as a function of time is described by y(t) = -9.81t^2 and that the horizontal position of the ball as a function of time is described by x(t) = 2t. Find the second derivative of y with respect to x: d^2y/dx^2.
A particle moves on the xy-plane. The following equations about the particle’s movement are true: dy^2/dx^2 = 2t^4 + 6t^2 + 3t and dx/dt = 1/t. Find y(t) given that y(0) is 25.
What is the displacement of a parametric function defined by x(t) and y(t)?
