Rotational Motion PHYS_111 (1)

A planet is in a circular orbit around a star – its radius and speed are constant. Which of the following is constant? Which of the following is not constant? Explain why. a.    Kinetic Energyb.    Potential Energyc.    Linear Momentumd.    Angular Momentum

6. A body of m, moving at v along a smooth horizontal surface, collide with a horizontally spring with a spring constant k (see figure). The maximum compress value Al for the spring 1). Al = v k 2). Al = v 3) Al = vvmk 4) Al = v/Vmk 7. The first cosmic velocity for a planet is v. T. The another planet radius is n times the radius of the first planet, and the average density is the same. The first cosmic velocity for another planet a) vz = Vnv b) v, = nk с) и, %3D vn d) 8. A ball of mass m, half immersed in water, floats in it. If the density of water is p0, the density of oil is p1, the buoyancy to the ball if it is in oil will be a) F=pomg/2p1 b) F=mg c) F=mg/2 d)F=pimg/2po ||

NASA is expected to send a 2600-kg satellite 450 km above the earth's surface. a.) What is it's radius? b.) What speed will it have?(hint: Earth's mass is 5.97x10²⁴ kg) c.) What is it's orbital period? d.) What is it's radial acceleration?
