- Consider the Earth and the Moon as a two-particle system. a. Find an expression for the gravitational field g of this two-particle system as a function of the distance r from the center of the Earth. (Do not worry about points inside either the Earth or the Moon.) b. Plot the scalar component of g as a function of distance from the center of the Earth.arrow_forwardTo give a pet hamster exercise, some people put the hamster in a ventilated ball andallow it roam around the house(Fig. P13.66). When a hamsteris in such a ball, it can cross atypical room in a few minutes.Estimate the total kinetic energyin the ball-hamster system. FIGURE P13.66 Problems 66 and 67arrow_forwardTwo children, with masses m1 = 35.0 kg and m2 = 43.0 kg, are swinging on a tire swing attached to a tree overhanging a pond. The mass of the tire is negligible. At the lowest point of the swinging motion, the tension in each of the three vertical 4.00-m-long chains supporting the swing is 275 N. a. What is the speed of the children at the lowest point of the swinging motion? b. What is the force exerted on each child by the tire at the lowest point of the swinging motion?arrow_forward
- Does the kinetic energy of an object depend on the frame of reference in which its motion is measured? Provide an example to prove this point.arrow_forwardAn open box slides across a frictionless, icy surface of a frozen lake. What happens to the speed of the box as water from a rain shower falls vertically downward into the box? Explain.arrow_forwardA system consists of three particles, each of mass 5.00 g, located at the corners of an equilateral triangle with sides of 30.0 cm. (a) Calculate the gravitational potential energy of the system. (b) Assume the particles are released simultaneously. Describe the subsequent motion of each. Will any collisions take place? Explain.arrow_forward
- NT51-QRT104: TWO OBJECTS— GRAVITATIONAL FORCE ON EACH The drawing to the right shows an object (labeled B) that has mass m. To the left is another object (labeled A) that has mass 2m. Identify the pair of force vectors (the arrows) that correctly compare the gravitational force exerted on A by B with the gravitational force exerted on B by A Please show all work and explainarrow_forwardQ29- AB A and BIt is known as the scalar product of vectors. Which or which of the following are attributes of this product?1) The product of the product is a vector.II) The result depends on the angle between the two vectors.III) If the two vectors lie in exactly the opposite direction, the result is zero.OA)OB) I and IIIC)OD) IIIE) Il and IIIarrow_forwardA 1.21 kg block B is moving with a speed of 2.23 m/s as it strikes the 0.69 kg sphere A which was at rest. If the speed of the block was reduced to 1.21 m/s immediately after impact, compute the height (m) reached by the sphere. Round off only on the final answer expressed in 3 decimal places.arrow_forward
- Just a little something on momentum and kinetic energy. As a reminder, momentum is a vector and: p = mv K = 1/2 mv2 = 1/2 pv = p2/2m In terms of the dot product: v2 = v⋅v, p2 = p⋅p, and pv = p⋅v. Unlike speed vs. velocity, but like all other vectors, momentum may refer to the magnitude of the momentum vector. Now, answers the following questions: 1) A 7-kg particle goes 96 m/s. Calculate its momentum in kg*m/s. (This requires an exact answer.) 2) A 7-kg particle's momentum is (392, 61) kg*m/s. Calculate its kinetic energy. 3) A pebble and a grapefruit have the same momentum. Which has the greater kinetic energy?arrow_forwardTwo objects (m1 = 5.35 kg and m2 = 3.10 kg) are connected by a light string passing over a light, frictionless pulley as in the figure below. The 5.35-kg object is released from rest at a point h = 4.00 m above the table. Two objects are connected by a taught string passing over a pulley. An object labeled m2 rests on a table, and an object labeled m1 dangles a distance h above the table. (a) Determine the speed of each object when the two pass each other.m/s(b) Determine the speed of each object at the moment the 5.35-kg object hits the table.m/s(c) How much higher does the 3.10-kg object travel after the 5.35-kg object hits the table?arrow_forward1.A plate drops onto a smooth floor and shatters into three pieces of equal mass. Two of the pieces go off with equal speeds v at right angles to one another. Find the speed and direction of the third piece. Explain and labled the problem.arrow_forward
