Answer:

The coefficient of friction is 0.05

Explanation:

Given that,

When Isabella pushes a box of mass 5.25 kilograms with a force of 15.7 newtons.

It accelerates by a rate of 2.50 m/s²

Let coefficient of friction be μ

Force (F) = 15.7 N

Acceleration (a) = 2.5 m/s²

Mass (m) = 5.25 kg

Gravity (g) = 9.8 m/s²

Balanced equation of box to move

F - μmg = ma

15.7 - μ(5.25)(9.8) = (5.25)(2.50)

\mu = \dfrac{15.7-5.25\cdot 2.5}{5.25\cdot 9.8}

\mu = 0.05

Hence, The coefficient of friction is 0.05

Resultant force on the box = mass x acceleration

Sigma F = ma

Fr: friction force

15.7 - Fr = 5.25 x 2.5

15.7 - Fr = 13.125

Fr = 15.7 - 13.125 = 2.575 N

The magnitude of the weight of a 3.0 kg object on the surface of the earth is 29 N. True False
madreJ [45]
True

In fact, the weight of an object on the surface of the Earth is given by:
F=mg
where m is the mass of the object and g=9.81 m/s^2 is the gravitational acceleration on Earth's surface. If we use the mass of the object, m=3.0 kg, we find
F=mg=(3.0 kg)(9.81 m/s^2)=29 N

A student attaches a rope to his
erastova [34]

The choices are:

a. Normal Force

b. Gravity Force

c. Applied Force

d. Friction Force

e. Tension Force

​f. Air Resistance Force

Answer:

The answer is letter e, Tension Force.

Explanation:

Force refers to the "push" and "pull" of an object, provided that the object has mass. This results to acceleration or a change in velocity. There are many types of forces such as <em>Normal Force, Gravity Force, Applied Force, Friction Force, Tension Force and Air Resistance Force.</em>

The situation above is an example of a "tension force." This is considered the force that is being applied to an object by strings or ropes. This is a type force that allows the body to be pulled and not pushed, since ropes are not capable of it. In the situation above, the tension force of the rope is acting on the bag and this allows the bag to be pulled.

Thus, this explains the answer.

Find the velocity, acceleration, and speed of a particle with the given position function. r(t = t2i 6tj 4 ln t k
artcher [175]
1st derivative gives velocity;
d r(t)/ dt = 2t i + 6 j + 4/t k

2nd derivative gives acceleration;
d^2 r(t)/ dt^2 = 2 i - 4/ t^2

Speed ;
Square root of (4 t^2 + 36 + 16/ t^2)

For a given time, like 2 seconds, t will be 2. And answer of speed will be scalar.
