Answer:
The coefficient of static friction between your partner and the floor is 0.55
Explanation:
Given:
Mass Kg
Frictional force N
From the formula of frictional force,
Where coefficient of static friction,
Put the above values and find the coefficient of static friction.
Therefore, the coefficient of static friction between your partner and the floor is 0.55
The energy of the baby is gravitational potential energy, and it is equal to the weight of the baby times its height from the ground:
where
mg=20 N is the weight (the mass times the gravitational acceleration)
h=1.5 m is the height from the ground
If we plug the numbers into the equation, we find
