Question

If the horse reared up on two legs, what effect would it have on the pressure?
(a) It will exert half the pressure it did before
(b) It will exert the same pressure it did before
(c) It will exert twice the pressure it did before
(d) It will exert four times the pressure it did before

Answer 1

Answer:

c) it will exert twice the pressure it did before.

Explanation:

Pressure is Force per unit Area. Here the mass of the horse remains the same but since its on two legs instead of four, the area reduces to half which causes the pressure to become double.
