Steve is standing atop a mountain watching an airplane fly by. There is a strong wind blowing at 125°CW from North at 500 m/s. Jim is on an airplane pointed due west, moving at 2000 m/s. Jim's airplane has a mass of 3000 kg. i) ii) What is the planes velocity (direction and magnitude) relative to Steve? What is the kinetic energy of the airplane from Jim's perspective? From Steve's? Jim turns on the airplane's headlights, what does Steve measure...

A 3.70 kg object is attached to a spring and placed on frictionless, horizontal surface. A horizontal force of 19.0 N is required to hold the object at rest when it is pulled 0.200 m from its equilibrium position (the origin of the x axis). The object is now released from rest from this stretched position, and it subsequently undergoes simple harmonic oscillations (a) Find the force constant of the spring, N/m (b) Find the frequency of the oscillations Hz...

A 0.32-kg puck at rest on a horizontal frictionless surface is struck by a 0.22-kg puck moving in the positive x-direction with a speed of 6.6 m/s. After the collision, the 0.22-kg puck has a speed of 1.6 m/s at an angle of € = 60° counterclockwise from the positive x-axis. (a) Determine the velocity of the 0.32-kg puck after the collision. magnitude After writing a statement of conservation of momentum in the x and y directions, you will have...
