Two children make a seesaw out of a 5.0-m wooden plank. They balance it on a fulcrum located 2.0 m from the left end. The 42.0-kg child sits at the end of the plank on the left side. What distance (measured from the fulcrum) can the 35-kg child sit on the
A skier weighing 70 kg pushes off from the top of a ski slope with a force of 105 N directed down the slope. The slope is inclined at 30°.Assuming that the slope is frictionless, what is the initial rate of the skiers acceleration during the push-off?
A snowball just begins to slide down a hill when the angle between it and the horizontal is 25°. Calculate the coefficient of static friction.
Calculate the tension and acceleration in the pulley system shown below assuming there is not friction.
A cylinder has a moment of inertia, I. How much time does it take a torque, t, to increase its angular speed from w1 to w2?
A body of mass 1kg is attracted by the earth with a force , which is equal to ?
Two satellites of equal mass orbit a planet. Satellite B orbits at twice the orbital radius of Satellite A. The gravitational force on Satellite A ................. that on Satellite B.
A block with a mass of 30 kg is hanging still from a string. If you place another block with a mass of 10 kg at a distance of 2 m away, what is the gravitational attraction between the two blocks?
A block with a mass of 30 kg is located on a horizontal, frictionless tabletop. This block is connected by a rope to another block with a mass of 10 kg. The rope is looped through a pulley on the tables edge so that the less massive block
A 1000-kg satellite orbits the Earth in a circular orbit at an altitude of 1000 km. The Earths mass is 6.0 X 10^24 kg, and its radius is 6.4 X 10^6 m.-How does the force of gravity on the satellite compare with the centripetal
