The true statement according to Newton's laws of motion is; "there is no net force on the block during the 2nd second as zero net force keeps the motion constant."
According to the Newton first law of motion, an object will continue in its state of rest or uniform motion unless it is acted upon by a net force. The action of a net force leads to an acceleration.
In the 2nd second of the journey, there is no net force on the block hence the block continues to move at constant velocity.

The resultant of the vectors is .
<h3>What is a resultant vector?</h3>
A resultant vector is the vector sum of two or more vectors.
The given vectors;
- Height of vector A = HA
- Height of vector B = HB
- Height of vector C = HC
The height of vector B is the resultant of the three given vectors.
When the vectors are drawn from head to tail, the vector B forms the resultant of the two other vectors (A and C).
Thus, the resultant of the vectors is .

Would that be 10?
.1 second per revolution, so 10 rps
Answer:
Given: Initial Velocity:0
Velocity: 25 m/s
Time :10 sec.
Acclereation?.
Use formula for acceleration,
Divide units to
So our acceleration is
If you want to, you can use kinematic equation
vi is inital velocity, since v1=0 we just have
Which is the same as first step, so we would get 2.5 m/s^2
Answer:
The Normal Force is zero.
Explanation:
The reason for the normal for to be zero is because no matter if the is a form of contact at the top, the is no force applied by the cart to loop-de-loop, and so vice versa.
If the cart was on the bottom, then the normal force would be equal to the weight of the cart, which would be te force the cart would be applying to the loo-de-loop, and therefore by newton's third law, the loop-de-loop would apply an equal force to the cart, which we would say is the normal force.
