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.
