An object is dropped from a height of 15 feet. Use the position equation s = -16t² + v₀t + s₀ to write a function that represents the situation and select the graph of the function. A)s = -16t² + 15t B)s = -16t² + 15 C)s = -16t² - 15t D)s = 16t² + 15 E)s = -16t² - 15

Question

The position equation for an object in free fall is s = -16t^2 + vt + s0, where s0 is the initial height and v is the initial velocity. Since the object is dropped, the initial velocity is 0. So, the equation becomes s = -16t^2 + 15. This equation matches with option B, so B is the correct choice.
