- Use G = 6.674 × 10-¹1 N m²/kg² to answer below questions. a. Evaluate the gravitational potential energy between two 5.00-kg spherical steel balls separated by a center-to-center distance of 16.1 cm. Hint (a) U = ×10-8J b. Assuming that they are both initially at rest relative to each other in deep space, use conservation of energy to find how fast will they be traveling upon impact. Each sphere has a radius of 5.4 cm. Hint (b) x10-5 m/s V=Planetary motion. A planet or asteroid orbits the Sun in an elliptical path'. The diagram shows two points of interest: point P, the perihelion, where the planet is nearest to the Sun, and the far point, or aphelion, at point A. At these two points (and only these two points), the velocity v of the planet is perpendicular to the corresponding "radius" vector ř, from the Sun to the planet. An arbitrary point Q is also shown. P AThree different objects, all with different masses, are initially at rest at the bottom of a set of steps. Each step is of uniform height d. The mass of each object is a multiple of the base mass m: object 1 has mass 4.60m, object 2 has mass 1.71m, and object 3 has mass m. When the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. If the objects are then relocated as shown, what is the new total potential energy of the system? Each answer requires the numerical coefficient to an algebraic expression. Each algebraic expression is given using some combination of the variables m, g, and d, where g is the acceleration due to gravity. Enter only the numerical coefficient. (Example: If the answer is 1.23mgd, just enter 1.23) This potential energy was calculated relative to the bottom of the stairs. If you were to redefine the reference height such that the total potential energy of the system became zero, how high…

The total work done by the force in moving the particle once around the ellipse is zero d. The force is conservative.Three different objects, all with different masses are initially at rest at the bottom of a set of steps. Each step is of uniform height d. The mass of the object is a multiple of the base mass: m: object one had mass 3.10m, object 2 has mass 1.46m, and object 3 has mass m. Object 3 is on step one, object 2 is on step two, and object one is on step 3. define the total gravitational energy of the three object system to be zero when the objects are at the bottom of the steps.

- Q19 The concept of escape velocity can be best described as: (A) The initial speed required so that an object will safely orbit the Earth. (B) The speed for an object to be launcned and fly through space forever. (C) The speed necessary for a spacecraft to escape Earth's atmosphere. (D) The velocity needed to provide an initial kinetic energy such that total mechanical energy is zero.A planet with a radius of 6.00 × 107 m has a gravitational field of magnitude 40.2 m/s2 at the surface. What is the escape speed from the planet? ____km/s4. Here we prove a version of the work-kinetic energy theorem for an object moving in 1-D subject to a constant force. Consider a mass m, traveling initially at speed v, on which a constant net force F is applied in the same direction as its motion over a distance d. After the net force has acted over this distance, the speed of the object is v2. In terms of m, F, v1, v2, and d only, V, A) What is the acceleration of the mass? t=0 m F d t>0_m B) What is the time over which the mass travels the V, distance d? [Use one equation of constant acceleration to find this.] C) Use another equation of constant acceleration to relate m, F, v,, v2, and d. Show that the product W = Fd is equal to the change in the mass’s kinetic energy.
