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

Quizplus · Accepted Answer

- The position equation for an object dropped from a height of 15 feet is s = -16t^2 + 15. 
- This matches option B: s = -16t^2 + 15. 
- Option A has an extra t term. 
- Option C and E have a negative coefficient for the t term, which means the object is moving downwards with increasing time, but in reality, the object is only moving downwards due to gravity. 
- Option D has a positive coefficient for the t term, which means the object is moving upwards with increasing time, but again, in reality, the object is only moving downwards due to gravity.
