Question

The mass of the box is 300 kg and its base area is 15msquare.Calculate the pressure exerted by the box on the ground(ground=9.8m/s square.

Answer 1

Answer:

196 Pa

Explanation:

ATQ,

Mass of box = 300kg

acceleration due to gravity = 9.8m/s2

Area of base = 15m2

Therefore, the net force acting on it = M x a

                                =  300 x 9.8

                              = 2940  N

Now, pressure = force/area

   =  2940/ 15

  =   196  Pa

HOPE THIS HELPS YOU...
