Question

4. Two blocks, kept on a surface of inclination 30°, are
connected by a weightless string. Each block is of mass
1 kg. Coefficients of friction of the lower and the upper
block with the plane are 1 and respectively. If the
two blocks are released simultaneously, what will be
the common acceleration along the inclined plane?
What will be the tension in the string?

If the two blocks are released simultaneously, what will be the common acceleration along the inclined plane? What will be the tension in the string? [1.72 m.s-2 ; 1.06 N]

Answer 2

f1=m1gsin30−T+μ1R1 −−−−(1)

and

f2=m2gsin30+T+μ2R2−−−−(2)

hence

f1=m1a

and

f2=m2a

by solving it we get

T = 1.06

a = 1.72 m/s^2
