A satellite circles planet Roton every 2.3 h in an orbit having a radius of 1.2 ´ 107 m. If the radius of Roton is 5.0 ´ 106 m, what is the magnitude of the free-fall acceleration on the surface of Roton?
A 600 ball is attached to the spring and allowed to come to rest. It is then pulled down 6.90 and released. What is the time constant if the ball's amplitude has decreased to 3.20 after 30.0 oscillations?
Path A is 7.0 km long heading 60.0 degrees north of east.Path B is 6.0 km long in a direction due east. Path C is 5.0 km long heading 315 degrees counterclockwise from east. Graphically add the hikers displacements in the order A,B,C and give the
A 65.5 kg ice skater moving to the right with a velocity of 2.67 m/s throws a 0.19 kg snowball to the right with a velocity of 21.7 m/s relative to the ground. What is the velocity of the ice skater after throwing the snowball?
