Final answer:
The force at which an object hits the ground is determined by its weight, which is calculated using its mass and the acceleration due to gravity. In this case, the force is 11025 Newtons.
Step-by-step explanation:
When an object falls to Earth, the force at which it hits the ground is known as its weight. Weight is determined by the mass of the object and the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s².
To calculate the force at which the object hits the ground, we can use the formula:
Weight = mass x acceleration due to gravity
In this case, the object has a mass of 1125 kg, so we can plug it into the formula:
Weight = 1125 kg x 9.8 m/s² = 11025 N
Therefore, the force at which the object hits the ground is 11025 Newtons. The force at which a 1125kg object hits the ground is its weight, calculated by multiplying its mass by Earth's gravity, resulting in a force of 11,025 Newtons.
