Final answer:
The rate at which a ball dropped on the surface of Katar accelerates towards the ground can be calculated using the formula for acceleration: acceleration = (gravity * radius), where gravity is the acceleration due to gravity and radius is the radius of Katar. Given that the radius of Katar is 2.61 x 107 m, you can use this value to find the acceleration rate. The direction of the acceleration is towards the center of the Earth.
Step-by-step explanation:
The rate at which a ball dropped on the surface of Katar accelerates towards the ground can be calculated using the formula for acceleration:
acceleration = (gravity * radius)
where gravity is the acceleration due to gravity and radius is the radius of Katar.
Given that the radius of Katar is 2.61 x 107 m, you can use this value to find the acceleration rate.
Plug in the values in the formula:
acceleration = (9.8 m/s² * 2.61 x 107 m)
Solving this calculation will give you the rate at which the ball accelerates towards the ground.
acceleration = 2.56 x 108 m/s²
The direction of the acceleration is towards the center of the Earth.
