The net force on the sledge is 31.64N.
Frictional force = µkR
= 0.269 x 42.2 x 9.81 = 111.36
net force = 143N - 111.36N
= 31.64N

It is dependent upon the object's mass. The greater the mass of the object greater will be the inertia of the object, and hence it's resistance to change in motion as well.
The correct answer to this question would be trees.
2940N
Explanation:
Given parameter:
Mass of the human = 300kg
Unknown:
Weight of human on earth.
Solution:
Mass is a fundamental quantity that measures the amount of matter contained in a substance.
Weight of a body is the force that is acting on it due to the gravitational pull
Weight = mass x acceleration due to gravity
acceleration due to gravity = 9.8m/s²
Inputting the parameters:
Weight = 300 x 9.8 = 2940N
