Find the magnitude of the impulse delivered to a soccer ball when a player kicks it with a force of 1450 n . assume that the player's foot is in contact with the ball for 5.50×10−3 s .

Determine the time it takes for a satellite to orbit the earth in a circular "near-earth" orbit. the definition of "near-earth" orbit is one which is at a height above the surface of the earth which is small compared to the radius of the earth, so that you may take the acceleration due to gravity as essentially the same as that on the surface. does your result depend on the mass of the satellite?
