The equation h=7cos(pi/3 t) models the height h in centimeters after t seconds of a weight attached to the end of a spring that has been stretched and then released. a. Solve the equation for t. b. Find the times at which the weight is first at a height of 1 cm, of 3 cm, and of 5 cm above the rest position. Round your answers to the nearest hundredth. c. Find the times at which the weight is at a height of 1 cm, of 3 cm, and of 5 cm below the rest position for the second time. Round your answers to the nearest hundredth.
so which one don't you know?
all of it. i don't understand this.
not even solve for t?
have you atleast tried it
i have seen this question before, and wonder where it comes from, because something is wrong with it
whats wrong with it? its a simple harmonic motion problem
for one thing, how is a height negative?
lol i havent solved it yet tho but it can i think; since its a cosine curve and the amplitude can be a negative
