2 4. A 400-kg satellite circles the earth at a distance of 8.00 x 10 m away from the center of the earth. What is the magnitude of the gravitational force, Fo, on this satellite, and what is the speed, v, of the satellite along its circular path (if one may take for the mass of the earth, ME = 5.98 x 1024 kg, and for the gravitational constant, G = 6.67 x 10-1 N.m2/kg2)? 5. A 2.00-kg block, initially at rest on a frictionless horizontal surface, is attached to a (massless) horizontal spring, having a spring constant of 300 N/m, as sketched below. The initial compression of the spring is 6.00 x 10-2 m. What are the magnitude of the initial acceleration, a, of the block when it is released, and the speed, v, of the block after the spring is relaxed-neither compressed nor stretched from its "natural" length? more 2.00 Kq 6. Starting from rest, a 3.00-kg box slides downward along a frictionless inclined plane that makes an angle of 10.0 with respect to the horizontal direction, as seen sketched below. How much work, W, does the gravitational force do on this box as its elevation decreases by 0.150 m, and what is the speed, v, of the box at this lower elevation (if one may take for the gravitational acceleration, g = 9.80 m/s2 downward, and neglecting any effects due to air resistance)? 3.00 0. 150 m (10.00
