A hammer is made of a solid sphere and a solid rod of negligible mass attached to the sphere. The radius of the sphere is R=25.0 cm and its mass is m=0.100 kg. The distance from the center of the sphere to the pivot is l=1.00 m. The hammer is released from it is initial position at the angle ϕ=30° with the vertical direction (see Figure below). Find the velocity of its center of mass at the lowest point. The moment of inertia of a solid sphere is 2mR2/5 about the axis through any diameter.
The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at ??,2=16.1 m/s when the eagle swoops down, grabs the pigeon, and flies off. At the instant right before the attack, the eagle is flying toward the pigeon at an angle ?=39.9°below the horizontal and a speed of ??,1=40.5 m/s. What is the speed of the eagle immediately after it catches its prey? speed: m/s What is the magnitude of the angle, measured from horizontal, at which the eagle is flying immediately after the strike? magnitude of angle: °
In the figure, two particles are launched from the origin of the coordinate system at time t - O. Particle 1 of mass m₁ - 5.20 g is shot directly along the x axis (on a frictionless floor), where it moves with a constant speed of 10.7 m/s. Particle 2 of mass m₂ -4.50 g is shot with a velocity of magnitude 15.6 m/s, at an upward angle such that it always stays directly above particle 1 during its flight.
