Question

Example 11. A block of mass 200 kg is set into
motion on a frictionless horizontal surface with the
help of frictionless pulley and a rope system as shown
in figure (a). What horizontal force F should be
applied to produce in the block an acceleration of
1 m/s??
a = 1 m/s2

I don't understand how the pulley is working. can you please explain its urgent
​

Answer 1

Step-by-step explanation:

force on the block(bcz string constants) is 2F then

2 F= 200

F=100
