air traffic controllers usually describe the position of an aircraft relative to the airport by altitude, horizontal distance, and bearing. Suppose an aircraft is at altitude 500 m, distance 15 km, and bearing 35 degrees east of north. What are the x, y, and z components (in meters) of hte position vector? The x axis is east, the y axis is north, and the z axis is vertical.
The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.8 m/s as it passes through the lowest point. Illustrate what is the tension in the rope at that point?
Calculate the y-component of the magnetic force.
A 1.00-kg glider attached to a spring with a force constant of 25.0 N/m oscillates on a horizontal, frictionless air track. At t = 0 the glider is released from rest at x = -3.00 cm.
Consider a car driving at constant velocity. The force of friction acting on the car in Newtons is, Find the magnitude of f when v = 50 miles/h
Seismographs measure the arrival times of earthquakes with a precision of 0.100 s.7 To get the distance between to the epicenter of the quake, they compare the arrival times of S- and P-waves, which travel at different speeds.
