If you weigh 660 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 16.0 km ? Take the mass of the sun to be ms = 1.99×1030 kg , the gravitational constant to be G = 6.67×10−11 N⋅m2/kg2 , and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2 . Express your weight wstar in...

Three identical small Styrofoam balls of mass 1.96 g are suspended from a fixed point by three nonconducting threads, each with a length of 47.2 cm and negligible mass. At equilibrium the three balls form an equilateral triangle with sides of 28.3 cm. What is the common charge carried by each ball? The acceleration due to gravity is 9.8 m/s2 and the value of Coulomb’s constant is 8.98755 × 109 N · m2/C2 .

A mass weighing 20 N stretches a spring 6 m. The mass is initially released from rest from a point 8 m below the equilibrium position. (a) Find the position x of the mass at the times t = 7/12, 7/8, 1/6, 1/4, and 97/32 s. (Use g = 9.8 m/s2 for the acceleration due to gravity.) x(1/12) = 7.56 E * *(1/8) = 7.02 E * (1/6) = 6.29 E * x(/4) = 4.34 E * (97/32) = 3.47...

Based on what you know about falling objects, select all of the correct statements from the following list. (Ignore the effects of air resistance.) a. The speed of a falling object depends on its weight. b. Objects tend to slow down naturally unless propelled by a force. c. According to tradition, Galileo dropped objects of different mass from the leaning tower of Pisa. d. Inertia is an object's tendency to resist changes in its motion. e. The speed of falling...

A circus act consists of a performer (a "human cannonball") being launched from a cannon into a net at the other end of the stage. The performer (mass 60 kg) leaves the cannon at a speed of 25 m/s at an angle of 30o above horizontal. She comes out of the cannon at a height of 2 meters above the ground and lands in the net at a horizontal distance of 45 meters away from the launch point. Let +x...
