The body senses whether it is upright or lying down or whether it is moving or standing still through the vestibular system, which is in the upper portion of the inner ear.
On sources it says it would just be the super giant star
Answer:
20,850 N
Explanation:
We can solve the problem by using second Newton's Law:

where
F is the force
m is the mass
a is the acceleration
In this problem, we have:
m = 70 kg is the mass
is the acceleration (which is negative, because it is a deceleration)
So, we can use the equation above to find the force:

and the negative sign simply means that the force is in the opposite direction to the motion.
Answer:
a) The net force acting on the sleigh is zero because it is moving at a constant speed.
b)
, then
