Two identical blocks, each of mass m=5 kg, are connected by a light string, over a pulley of radius R and mass
m. The coefficient of kinetic friction between the plane and sliding block is u= 0.25. The lower block falls down
from a height h= 0.4 m before it hits the ground. Assume that the system is released at time t-0. (The moment
of inertia of the pulley is l-mR²/2)
) What is the acceleration of two blocks?
) What are the tensions in the lower and upper sections of the string?
What is the speed of the block when it hits the ground?
