QUESTION 226 (5 marks)

A 2 kg block is projected up a smooth plane at 6 m/s. The plane is inclined at 30 degrees to horizontal. Take g=10 m/s squared and up-plane displacement positive.
A block on a smooth 30-degree incline. Weight and normal reaction arrows start at a single node in the block centre. An arrow beside the slope indicates positive displacement uphill.
a)
