Question
Two blocks with masses Mj and M2 are connected by a
massless string that passes over a massless pulley as shown.
M1 has a mass of 2.25 kg and is on an incline of 01
41.5°
with coefficient of kinetic friction uj = 0.205. M2 has a mass
of 5.35 kg and is on an incline of 02 = 34.5° with coefficient
of kinetic friction u, = 0.105. The two-block system is in
motion with the block of mass M2 sliding down the ramp.
Find the magnitude a2 of the acceleration of M2 down
the incline.
a2 =
m/s?

The large block shown is x = 16.0 cm wide, y = 20.0 cm
long, and z = 27.00 cm high with a mass of 2.55 kg. This
block is passing through air (density of air Pair = 1.43kg/m³).
Calculate the terminal velocity of the block if it is traveling
downward with a drag coefficient of I = 0.862. See the hint
panel for the drag force equation.
