Explanation / Answer

The question values are not visible properly but assume m = 52kg. A= 0.0063m2 (if these values are not correct then use correct values as per question - method is same)

Part a) Force exerted on ice = F =mg

Part b) F =52 x 9.81 = 510.12N

Part c) Pressure on the ice is P =F/A

Part d) P = 510.12/0.0063 = 80971.428 N/m2
