Standing on four paws, the dog exerts a pressure of 150 kPa on the ground. Standing on two paws, the dog will exert pressure.

To find the pressure that the dog in question will exert while standing on two legs, we use the equality: P1 * 4S1 = Fт (effective gravity) = P2 * 2S1, whence we express: P2 = P1 * 4S1 / 2S1 = P1 * 2.

Variable values: P1 – pressure exerted by the dog on four legs (P1 = 150 kPa).

Calculation: P2 = P1 * 2 = 150 * 2 = 300 kPa.

Answer: On two paws, the dog in question will exert a pressure of 300 kPa on the ground.
