A rock is thrown upward from a bridge into a river below. The function f(t)=−16t2+44t+88 determines the height of the rock above the surface of the water (in feet) in terms of the number of seconds t since the rock was thrown.
What is the bridge's height above the water?
feet
How many seconds after being thrown does the rock hit the water?
seconds
How many seconds after being thrown does the rock reach its maximum height above the water?
seconds

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
