An astronaut wandering the solar system encounters a 726 kg steel block resting

on a surface where (meau) s = 0.650 and k = 0.400. An attempt by the astronaut to set

the steel block in motion across the surface requires a force of 4930 N. On

which planet is this astronaut wandering? Support your answer with calculations.

Respuesta :

Answer:

Therefore the planet is Saturn .

Explanation:

Let acceleration due to gravity be g .

weight on the planet = 726 g

Frictional force = μs mg

= .65 x 726 x g

This force is equal to 4930 N .

.65 x 726 x g = 4930 N .

g = 10.44 .

Therefore the planet is Saturn .
