Abullet of mass m= 10 gram strikes a ballistic pendulum of mass m=2.0 kg. the center of mass of the pendulum rises a vertical distance of h=12 cm. assuming the bullet remains embedded in the pendulum, calculate its initial speed.

When you turn on a battery-operated device, an electrical circuit is

What determines the amount of inertia an object has

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
