(a)[2]
Calculate the pressure exerted on the ground by the block.
(b)[1]
State why the total pressure on the ground below the block is greater than the result in (a).
(c(i))[1]
Since the block has uniform density, State the height above the ground of the block’s centre of mass.
(c(ii))[2]
The block is turned about its lower, left-hand edge until it comes to rest on one of its smallest sides, as shown in Fig. 3.2. Explain why work is done while the block is being rotated.
