In the given arrangement, strings and pulleys are light and all surface are frictionless. Assuming at t = 0, system is released from rest, find the speed of block A (in decameter/sec) at t = 2 sec.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(1)
Sol . The system can be redraw as
a = 
= 
= 5m/s 2 
v = u + at = 2 × 5 = 10 m/s
