Suppose you want to throw a dart across a room at a wall-mounted
target and hit the target exactly at its center point. We call this
center point of the target its “bull’s-eye”. The bull’s-eye is a
horizontal distance d from the dart’s point of release and a height
habove the dart’s point of release. To hit the bull’s-eye, you have
a choice of the speed v at which you throw the dart and a choice of
the angle θ...
I don't understand 1a also need help with b. Can you please
explain in detail.
Springs and Harmonic Motion Restoring forces that follow respect the form of Hooke's Law lead to simple harmonic motion. Everyday items, such as springs, exhibit this behavior. More fundamentally, many important physical systems can be modeled as being spring-like (e.g. molecular bonds), which makes harmonic motion the simplest model of motion that is still broadly applicable and easy to generalize.. A position vs. time graph...
