The auditors of Dunce Ltd signed the balance sheet of the company, which grossly overstated the value of the stockin-trade, at the end of each year. The auditors had relied, without further enquiry, on certificates regarding the value of the stock-in-trade which were issued by the company secretary. The company has now gone into liquidation and it is clear that the company has no assets to pay its creditors. Empire Bank Ltd alleges that it relied on Dunce Ltd’s financial statements for increasing the overdraft facilities to it. The auditors are now being sued by Empire Bank to make good the loss it has suffered for not being able to recover the money advanced to Dunce Ltd.Required:Advise the auditors on their potential liability for professional negligence.

（16分） 如图所示为摩托车特技比赛用的部分赛道，由一段倾斜坡道AB与竖直圆形轨道BCD衔接而成，衔接处平滑过渡且长度不计．已知坡道的倾角θ＝11.5°，圆形轨道的半径R＝10 m，摩托车及选手的总质量m＝250 kg，摩托车在坡道行驶时所受阻力为其重力的0.1倍．摩托车从坡道上的A点由静止开始向下行驶，A与圆形轨道最低点B之间的竖直距离h＝5 m，发动机在斜坡上产生的牵引力F＝2750 N，到达B点后摩托车关闭发动机．已知sin11.5°＝，g取10 m/s²，求：

(1) 摩托车在AB坡道上运动的加速度；

(2) 摩托车运动到圆轨道最低点时对轨道的压力；

(3) 若运动到C点时恰好不脱离轨道，求摩托车在BC之间克服摩擦力做的功．
