A 15kg rectangular block with a length of 70cm and a width of 40cm rest on a table that pressure does the book exert on the table

Answer:

To determine the pressure exerted by the rectangular block on the table, we can use the formula for pressure:

Pressure = Force / Area

First, we need to calculate the weight of the block to find the force it exerts on the table. The weight (force due to gravity) can be calculated using the formula:

Weight = Mass x Acceleration due to gravity

Weight = 15 kg x 9.8 m/s^2

Weight = 147 N

The weight of the block is 147 Newtons.

Next, we need to find the area of contact between the block and the table. The area is equal to the length multiplied by the width of the block:

Area = Length x Width

Area = 70 cm x 40 cm

Area = 2800 square cm = 0.28 square meters (converted to square meters)

Now, we can calculate the pressure:

Pressure = 147 N / 0.28 m^2

Pressure ≈ 525 N/m^2

Therefore, the pressure exerted by the 15 kg rectangular block on the table is approximately 525 Newtons per square meter.
