Compressed air in an inflatable lifting mat is used to raise a concrete panel.
The pressure of the compressed air is 160 000 Pa160\,000\ \text{Pa}160000 Pa.
The top surface of the mat measures 75 cm by 40 cm. Only 80% of this surface is in contact with the panel.
Calculate the force that the mat exerts normal to the panel.
