Problem 2.88

A package is dropped from a helicopter that is descending steadily at a speed v0. After t seconds have elapsed, (a) what is the speed of the package in terms of v0, g, and t? (b) What distance d is it from the helicopter in terms of g and t? (c) What are the answers to parts (a) and (b) if the helicopter is rising steadily at the same speed?

Step-by-Step Solution:
Step 1 of 3

Harmonic Motion (14.1 - 14.6) Oscillating with sinusoidal motion (a sin or cos pattern) = simple harmonic motion → Periodic : Starts at one point and comes back to it Harmonic Oscillators : ● Mass on spring ● Pendulum ● Electrical Circuits ● Vibration in Solid Molecules → Amplitude (A) : Maximum displacement………………. SI Unit is m → Period (T) : time for one full cycle……………………...SI Unit is s → Frequency (f) : Inverse of T (1/T).................................SI Unit is Hz or Hertz Period is INDEPENDENT of Amplitude (for a given oscillator) 2π Sinusoidal Function : x(t) = Acos(Tt) = Acos((2πf · t) + ϕ) 2π = Acos(ωt
