A satellite is in orbit around a planet with orbital speed determined to be 2010 m/s. Find the escape velocity from the planet from this position of its orbit.
In the system shown in figure. A horizontal force Fx with a magnitude of 100N acts on object of mass m2=6.15kg. The horizontal force is frictionless. ( Picture- a flat table with mass m2 connected with a string to a pulley and mass 1 hangs off the ta..
A parachutist descending at a speed of 10.0 m/s loses a shoe at an altitude of 30.0 m. (Assume the positive direction is upward.). Explain when does the shoe reach the ground? What is the velocity of the shoe just before it hits the ground?

Assume that you wish to fabricate a uniform wire out of0.800 g of copper. If the wire is to have a resistance R = 0.400 , and if all of the copper is to be used. What will be the length of the wire? What will be the diameter of the wire?
A 0.500 kg football is thrown toward the east with a speed of 10.0 m/s. A stationary receiver catches the ball and brings it to rest in 0.020 s. What is the average force exerted on the receiver
What does it mean to say that two sources of waves are coherent, for instance, the waves in questions 2 above? If the sources in question 2 were two flashlights, would you observe interference at P? Explain.
A loop of area 0.02 m^2 is perpendicular to a magnetic field which changes from 2 T to 1.5 T in a time of 0.4 sec. What is the average voltage induced in the loop

The length of a simple pendulum is 0.86 m and the mass of the particle (the "bob") at the end of the cable is 0.33 kg. The pendulum is pulled away from its equilibrium position by an angle of 9.0 ° and released from rest.
A space probe is launched from Earth, headed for deep space. At a distance of 15,000 miles from the Earth's center, the gravitational force on it is 800 lb. What is the size of the force when it is at 30,000 miles from the Earth's center?
questionsmall terrestrial bodies lacked gravity force which depends on mass to keep initial atmosphere supplied by its
How many cubic centimeters are in a cubic kilometer? The speed of sound in air at sea level is around 340m/s. Express this speed in mi/hr. The speed of light in a vacuum is about 3108m/s. Express this speed in both mi/hr and miles per second.
