Problem 9 m,r A solid ball of mass m and radius r sits at rest at the top of a hill of height H leading to a circular loop-the loop. The center of mass of the ball will move in a circle of radius R if it goes around the loop. The moment of inertia of a solid ball is Ibull--mr. (a) Find an expression for the minimum height H for which the ball barely goes around the loop, staying...

5. A 1000-kg car is at the top of a hill as shown, where its elevation above the bottom of the hill is 120 m. a. What is its gravitational potential energy? 120 m b. If the cart starts from rest and rolls down the hill with negligible friction and air resistance, what will its kinetic energy be when it reaches the bottom? c. What will be its speed when it reaches the bottom? Suppose instead that there is noticeable...

You push a box of mass 16.3 kg with your car up to an icy hill slope of irregular shape to a height 4.5 m. The box has a speed 12.3 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) before immediately falling off a sheer cliff to the ground (with no drag). (a) What is the speed of the box at the top of the...

You push a box of mass 22.6 kg with your car up to an icy hill slope of irregular shape to a height 4.3 m. The box has a speed 12 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before coming to a rest when hitting a box of mass 89 kg. The heavier box then falls off a sheer cliff...

A 2.0 kg mass sits on top of a vertical spring that has a spring constant k=100 N/m. A second 2.0 kg mass is dropped from rest starting 1.0 m above the first mass. The dropped mass sticks to the first mass (Velcro) and the masses begin to bounce up and down on the spring. What is the period of the oscillation? What is the amplitude of the oscillation? How much time elapses between the time the masses collide and...
