A jetliner is moving at a speed of 274 m/s. The vertical component of the plane's velocity is 50.0 m/s. Determine the magnitude of the horizontal component of the plane's velocity.
A 1.0 Kg mass on a 37 degree incline is connected to a 3.0 kg mass on a horizontal surface. The coefficient of kinetic friction between all surfaces is 0.10 and the pulley is frictionless and the applied force is F=12N.
A 5.00-g lead bullet traveling at 470 m/s is stopped by a large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet while the other half is transmitted to the tree, what is the increase in
The same object is located at the same distance from two spherical mirrors, A and B. The magnifications produced by the mirrors are mA = 3.8 and mB = 2.3. Find the ratio fA/fB of the focal lengths of the mirrors.
A dragster starts from rest and accelerates down the track. each tire has a radius of .32 m and rolls without slipping. at a distance of 384 m, the angular speed of the wheels is 288 rad/s. determine the linear speed of the dragster and the magnit
A 2000 kg car is slowed down uniformly from 17.0 m/s to 5.00 m/s in 5.00 s. (a) What average total force acted on the car during that time?
A 3.00-m-long, 370 kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 69 kg constuction worker stands at the far end of the beam. What is the magnitude of the torque
