A newly discovered planet has a mass of 7.88 x1026 kg, and has a satellite whose mass is 6.44 x 1011 kg. If the satellite's orbital radius is 325 kilometers, what is the gravitational attraction between them.
A 9.8 kg object oscillates at the end of a vertical spring that has a spring constant of 1.9 * 10^4 N/m. The effect of air resistance is represented by the damping coefficient b= 3.00 Ns/m.
A 200 N object is supported by two ropes. Rope 1 makes an angle of 35 degrees with the horizontal, What is the amount of tension in each rope
A 5.50kg mass traveling at 3.5 m/s on a fricktionless tabled suddenly collides, What will be the maximum compression of the spring after the composite collides into it
A stone is dropped into a river from a bridge 43.90 m above the water. Another stone is thrown vertically down 1.00 after the first is dropped. The stones strike the water at the same time.
