If the ramp exerts no friction force on the block : A 200-g block is pressed against a spring of force constant kN/m until the block compresses the spring 10.0cm. The spring rests at the bottom of a ramp inclined at 60.0 degrees to the horizontal. Using energy considerations, decide how far up the inc..

Rebounded to its maximum height after the collision : A 5.000kg mass starts from rest and slides down on an inclined plane, hits a bumper at the bottom of the inclined plane and bounces back up the inclined plane and comes to rest again. Through the collision with the bumper, 0.700J of energy is lost.

What is the average power generated with the lifting force : A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 730-kg helicopter rises from rest to a speed of 8.8 m/s in a time of 3.9 s. Through this time it climbs t..

Consider both vertical and horizontal forces : A police officer in hot pursuit drives her car during a circular turn of radius 300m with a constant speed of 80.0km/h. Her mass is 55.0kg. What are the magnitude and the angle (relative to vertical) of the net force of the officer on the car seat? (..

What is the angle of the source above the horizon : Astronomers observe a 60.0 * 10^6 Hz source both directly and by reflection from the sea. The receiving dish is 20.0m above the sea level. If the two waves interfere constructively at the location of the dish, what is the angle of the source above th..

What is the maximum speed of the microphone : A microphone is attached to a spring that is suspended from the ceiling. Directly below on the floor is a stationary 440 Hz source of sound. The microphone oscillates up and down in simple harmonic motion with a period of 2.0s.

What is the magnitude of vertical component of earths field : An astronaut is connected to her spacecraft by a 25-m-long tether cord as she and the spacecraft orbit Earth in a circular path at a speed of 3.0 x103 m/s. At one instant, the voltage gauged between the ends of a wire embedded in the cord is gauged t..

What is the angular frequency and period of the pendulum : A simple pendulum is made from a string that is 0.65m in length with a mass of 0.2kg attached to the free end. The mass is pulled to one side during a small angle and released from rest.
