Question

A boy weighing 490N stands on an ice skate, the blade of which is 0.5cm wide and 25cm long. What is the pressure exerted by the boy?

please give the answer in pascal
and solve area in meter square

Answer 1

I considered the blade to be of a rectangular shape.

Then the area is equal to length into breadth

Width is equal to 0.5 CM ie,0.005m

Length is equal to 25 centimetre that is 0.25 metre

Therefore the area is equal to 0.005 into 0.25ie 0.00125m^2

Pressure is equal to force by area

That is 490÷0.00125

=392000Pa

I hope that this is the answer please let me know.

Answer 2

Answer:

a block weighting 50 N is placed on a wooden plank of 0.5 m find the pressure exerted by the board on the ground
