Question

Diagram below shows a simple pulley system that is used to lift a weight m of 10 kg 
by application of a force F.  Assuming gravitational acceleration g = 10 m/s2
(a) the force F required to accelerate m to 2 m/s2 in an upwards 
direction. You may assume the wheel and rope are frictionless.
(b) the work done during the first 3 s assuming m was initially at rest.
Your solution should show ALL working out to attract full marks.
