This would be most representative of Newton’s first law of motion, an object will continuously move in a straight line at constant velocity until a force is applied on to the object.
Answer:
<em>2</em><em>, The spring would compress twice the length of </em><em>. </em>
Explanation:
The Spring force is an application of Hooke's law, and using the law of conservation of energy in a spring system, we can find the relationship between the compression length and velocity.
<h3>Step by Step Calculations</h3>
For a spring system, the conservation of energy can be applied using the formula below;
........................................1
Where k is the spring constant
is the distance
m is the mass and
v is the velocity
We have to make the distance the subject formula to know how it affects the velocity;
.....................................2
from the equation, it shows that the distance () is directly proportional to the velocity (v). This implies that when the distance increases the velocity also increases.
x ∝ v
Therefore when the initial speed is doubled to 2 v it will amount a double increase in the distance which is 2
Answer:
yes
Explanation:
By definition, the speed of an object is the rate of change of its position.Velocity, on the other hand, is the measurement of the rate and direction of change in the position of an object. Since it is a vector physical quantity, both magnitude and direction are required to define it
Do the data support or refute the hypothesis, normally, the data for the first part of the experiment support the first hypothesis.
<h3>What is a hypothesis test?</h3>
Hypothesis testing refers to the formal procedures used by statisticians to accept or reject these hypotheses. When trying to make decisions, it is convenient to formulate assumptions or conjectures about the populations of interest, which consist of considerations about their parameters.
As a result of this, we can see that from the complete text, there is a set of data which is used to show the force that is applied to a cart that causes the acceleration of the cart to increase which supports Newton's second law.

given that initial velocity is
deceleration is given as
now we have to find the distance covered in 16 s
so it will cover 137.6 m distance
part b)
in order to find the final speed
so its speed will be 6.2 m/s
