Question Not answered Not graded Given that a particular moving object's position is given by the equation p(t) = 45t - 55, what is the equation for the object's acceleration? Select one: 5 a. a ( t ) = 0 b. a ( t ) = 45 c. a ( t ) = −45 d. a ( t ) = −55
Question Not answered v(t) = -32t +110, what is the equation for the object's acceleration? Select one: 6 Not graded Given that a particular moving object's velocity is given by the equation v(t) = -32t +110, what is the equation for the object's acceleration? Select one:
Remember that the acceleration is the derivative of the velocity equation. But, velocity is the derivative of the position function. So, since you are given the position function, take the derivative once to get the velocity function. p(t) = 45t - 55 p'(t) = v(t) = 45 Now take the derivative of the velocity equation to ±nd acceleration. v'(t) = a(t) = 0

The distance of the omelette from the customer in feet is given by P(t) = 16t . 7 Not graded t is measured in seconds. The omelette will hit the ground in 5 seconds. With what velocity does the omelette hit the ground? Select one:
