A 7.5 kg block is placed on a table. If its bottom surface area is 0.6 m2, how much pressure does the block exert on the tabletop?
A 7.5 kg block is placed on a table. If its bottom surface area is 0.6 m2, 122.5 Pa pressure does the block exert on the tabletop. Solution: P = F/A = mg/A = (7.5 kg)(9.8 m/s^2)/(0.6 m^2) = 122.5 Pa (answer)

A car with a mass of 2,000 kilograms is moving around a circular curve at a uniform velocity of 25 meters per second. The curve has a radius of 80 meters. The centripetal force on the car is 15,625 N.
Solution:
Fc = (mv^2)/r (where, Fc=centripetal force)
Fc = (2,000 kg * 625 m/sec)/80 m
Fc = 1,250,000/80m

A 7.5 kg block is placed on a table. If it's bottom surface area is 0.6m2, the block exert 122.5 Pa on the tabletop.

Solution: P = F/A where F = mg; F = 7.5 ( 9.81) = 73.6 N; P = 73.6 N / 0.6 m^2 = 122.5 Pa.
