Answer:

C a basketball player pushes into another one and they both fall to the left

Explanation:

I believe his is the answer because I don't see any force and not enough reaction

The answer is C, or A basketball player pushes into another one and they both fall to the left.

Explanation:

Isaac Newton’s third law states that for every action, there is an equal and opposite reaction. In this instance, there is no reaction in opposition to the basketball players being pushed into each other. Both players fall to the left, and this means that there is no equal and opposite reaction. Therefore, this example does not display Newton’s third law of motion.

7. A mother pushes her 9.5 kg baby in her 5kg baby carriage over the grass with a force of 110N @ an angle

jasenka [17]

Weight of the carriage $=(m+M)g =142.1\ N$

Normal force $=Fsin(\theta) + W = 197.1\ N$

Frictional force $=\mu N=27.59\ N$

Acceleration $=4.66\ m\ s^{-2}$

Explanation:

We have to look into the FBD of the carriage.

Horizontal forces and Vertical forces separately.

To calculate Weight we know that both the mass of the baby and the carriage will be added.

So Weight(W) $=(m+M)\times g =(9.5+5)\ kg \times 9.8 =142.1\ Newton\ (N)$

To calculate normal force we have to look upon the vertical component of forces, as Normal force is acting vertically.We have weight which is a downward force along with $F_x$ , force of $110\ N$ acting vertically downward.Both are downward and Normal is upward so Normal force $=Summation\ of\ both\ forces$
