The mass of a box is 300 kg and it's base area is 15m². Calculate the pressure exerted by the box on the ground.

• Mass, m = 300 kg

• Area, a = 15 m²

• Acceleration due to gravity, a = 9.8 m/s²

To Find :

• The pressure exerted by the box on the ground

Solution :

We know that,

★ Pressure = Force/Area

For calculation of Pressure we will have to find the force acquired first

From Newton's 2nd law of motion :

★ Force = Mass × Acceleration

→ F = 300 × 9.8

→ F = 2940 Newtons

Put the value of Force in the formula of Pressure :

→ Pressure =  

→ Pressure = 196 Pascals

 The pressure exerted by the box on the ground is 196 Pascals.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
