- In this problem, you'll get practice using the following Dynamics techniques:
1) Analyzing the motion of an object using r, and theta components for Acceleration and Velocity (i.e Polar/Cylindrical Components)
2) Because the directions of Velocity and Acceleration are known, we can use right triangle geometry to find the radial and theta components to velocity and acceleration. This makes it much easier.
3) Using the constant-acceleration, Kinematic Equations to analyze the projectile motion of an object
Problem Statement:
A helicopter is traveling at a constant velocity in level flight. At the instant shown, the co-pilot releases a package from the helicopter. The radar tracking the helicopter records the angle of elevation to be 38 degrees, the elevation to be 5000 ft, and the angular velocity to be 0.037 rad/s. For
the instant shown, find: a) speed of the helicopter, b) the angular Acceleration being recorded by the radar, c) how far away from the radar will the package be upon landing on the ground.
Can you do more exam problems? Test is this Friday
Unfortunately I am busy with other things, apologies!
