To focus a camera on objects at different distances, the converging lens is moved toward or away from the film, so a sharp image always falls on the film. A camera with a telephoto lens (f = 185 millimeter) is to be focused on an object placed first at a distance of 3.5 meter and then at 47 meter. Obtain over what distance must the lens be movable?
An object of mass 3.00 kg, moving with an initial velocity of 5.00i m/s, collides with and sticks to an object of mass 2.00 kg with an initial velocity of ?3.00j m/s
A satellite moves in a circular orbit around the Earth at a speed of 6.1 km/s. Determine the satellite’s altitude above the surface of the Earth. Assume the Earth is a homogeneous sphere of radius 6370 km and mass 5.98 × 10^24 kg.
A small mass is stuck to a point on the rim of a rolling wheel(radius of r) .. which traces out a path called a cycloid. The position vector of this point is given by r(theta)= r(theta - sin theta)i +r(1-cos theta)j. For a wheel rolling with constant..
