Question

velocity to
m/bec Irom 2 m/sec. Assume pulleys
are frictionless and weightless.
[Ans. 8 = 5.89 m)
9. By using work energy equation, calculate the
velocity and acceleration of the block. A shown in
Fig. 12.31 after it has moved 6 m from rest. The
coefficient of kinetic friction is 0.3 and the pul-
leys are considered to be frictionless and weight-
less. Also calculate, the tension in the string
attached to A.
[Ans. V = 3.544 m/sec ; a = 1.046 m/sec2;
WA = 200N
А
BW, = 4001
