The appropriate response would be the hollow ball.The purpose for it has more kinetic energy at the last (2/3 as opposed to 2/5) so it will have more potential energy (more height) at the best. Pondering it, more inertia implies its less impervious to change meaning the hollow ball with more inertia wont need to stop as fast.
The reaction force in this situation occur once it hits the ground, and normal force from Earth's surface will push up on the ball with 1.4 N.
<em>The correct answer is option (</em><em>C</em><em>) </em>
<h3>
What is Newton's third law of motion?</h3>
Newton's third law of motion states that for every action there is equal and opposite reaction.
Mathematically, this law is given as;
Fa = Fb
where;
- Fa is the force applied by object A
- Fb is the reaction experienced by object B
The force applied by object is equal and opposite the reaction experienced by object B.
When an object placed on the floor, the weight of the object acts downward while the normal reaction of the object acts upwards.
Thus, if you drop a baseball and let it fall, gravity from Earth pulls down on the baseball with 1.4 N of force, the reaction force will occur once it hits the ground, as the normal force from Earth's surface will push up on the ball with 1.4 N.

Answer:
The answer is 80 Joules
Explanation:
Electrical energy = Q x V
Energy = 2 x 40
= 80
I just took the test and it was right :D
The correct answer is B.
I hope this helped! :D
Answer:
Acceleration is the rate of change of velocity. If an object is changing its velocity, its speed, or changing its direction, then it is said to be accelerating.
Explanation:
when you change directions or speed up you are accelerating (or decelerating) and when you change directions or speed its called velocity.
Answer:
<u>411.84 kg m/s</u>
Explanation:
Formula :
<u>Momentum = mass × velocity</u>
<u />
=========================================================
Given :
⇒ mass = 26.4 kg
⇒ velocity = 15.6 m/s
=========================================================
Solving :
⇒ Momentum = 26.4 × 15.6
⇒ Momentum = <u>411.84 kg m/s</u>
