Suppose that you release a small ball from rest at a depth of 0.730 m below the surface in a pool of water. If the density of the ball is 0.260 that of water and if the drag force on the ball from the water is negligible, how high above the water surface will the ball shoot as it emerges from the water? (Neglect any transfer of energy to the splashing and waves produced by the emerging ball.)

    A small spherical ball of density p and radius a is released from rest and falls under gravity in a viscous liquid of density pf and viscosity u. Its vertical position is denoted by z(t), and we choose the origin such that z(0) = 0. The ball is subjected to two forces: its weight corrected for buoyancy F, = (p-p Vg, where g is the acceleration of gravity pointing in the - z direction and V = 47a/3 is the...

    dye You release a steel ball with a mass of 2 kg. from rest at point A one meter above the center of a steel plate, which has a mass of 8 kg. The plate is suspended by four bungee cords, each having a spring constant k = 100 N/m. The coefficient of restitution between the ball and the plate, e, is 0.9. How far down will the plate travel after impact, and how high above the plate's initial suspended...

    Imagine that we release a rock of mass m (which is initially at rest) at the surface of a lake and measure its position and velocity as functions of time while it sinks. The rock moves under the influence of three forces: gravity, buoyancy, and viscous drag. Let y represent the vertical position of the sinking rock, with the surface of the lake at y -0, and positive y upwards The net force on the rock is F =-[m-mdisplaced where...

    A ball of mass 0.4 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below. The velocity of the ball as it leaves the kicker’s foot is 16 m/s at angle of 46◦ above the horizontal. The top of the fence is 4 m high. The ball hits nothing while in flight and air resistance is negligible. The acceleration due to gravity is 9.8 m/s^2. Determine the time it takes for...
