A barge floating in fresh water (? = 1000 kg/m3) is shaped like a hollow rectangular prism with base area A = 650 m2 and height H = 2.0 m. When empty the bottom of the barge is located H0 = 0.45 m below the surface of the water. When fully loaded with coal the bottom of the barge is located H1 = 1.75 m below the surface.
Part (a) Find the mass of the coal in kilograms.
The velocity component of the particle at x = 8.0 m is 2.8 m/s. Illustrate what is the acceleration component during this time interval?
A composite bar made from two different materials of equal cross-sectional areas are directly attached to each other making the bar a length of L = L1 + L2.
The skis have a thrust of 189 N and a coefficient of kinetic friction on snow of 0.1. Unfortunatately, the skis run out of fuel after only 9 s. Illustrate what is Sam's top speed?
