A block of wood weighing 0.900 N rests on a table. A bullet weighing 0.100 N traveling with a velocity of 100 m/s hits the block of wood and sticks in it. The velocity of the bullet-block combination after the collision is 10 m/s. The coefficient of kinetic friction between the rough block and the table is 0.800. a) How far will the block slide before it skids to a stop?

Equation:

Ff = μ FN

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?

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.
