Arrow Shot Rotational Motion

An archer shoots an arrow straight up into the air to hit a bird, with an initial speed \(v = {{ params_v }}\) \(\rm{ft/s}\). Their friend stands \(d = {{ params_d }}\) \(\rm{ft}\) away. Find the following information. Assume the arrow launches from the horizontal line of site of the friend.

Part 1

At \(t = {{ params_t }}\) \(\rm{s}\), what is \(\dot r\)?

Answer Section

Please enter in a numeric value in ft/s.

Part 2

At \(t = {{ params_t }}\) \(\rm{s}\), what is \(\dot \theta\)?

Answer Section
