What is the force of a object that has a mass of 7 kg and an acceleration of 6 m/s/s
Answer:
42 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
mass = 7 kg
acceleration = 6 m/s²
We have
force = 7 × 6 = 42
We have the final answer as
42 NHope this helps you

A force of 36 N pushes a box that is 12.2 kg. The box is sliding horizontally 2.6 m/s to the left. What is the coefficient of friction? (Could you draw a Force Diagram?)
The coefficient of friction on the box sliding to the left is 0.3.
The given parameters;
applied force , F = 36 Nmass of the box, m = 12.2 kgvelocity of the box, v = 2.6 m/sThe acceleration of the box is calculated as follows;
[tex]F = ma\\\\a = \frac{36}{12.2} \\\\a = 2.95 \ m/s^2[/tex]
The coefficient of friction on the box is calculated as follows;
[tex]\mu_k = \frac{a}{g} \\\\\mu_k = \frac{2.95}{9.8} \\\\\mu_k = 0.3[/tex]
Thus, the coefficient of friction on the box is 0.3.

how much is the velocity of a body when it travels 600m in 5 minutes ?
its answer is 2M/S
but I don't know solution to take this answer
Explanation:
Displacement= 600 m
Time= 5×60 = 300 sec
Velocity= Displacement/time
= 600/300
= 2 m/s
B. Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the
shuttlecock when it hits the ground? Show your work below.
We have that the instantaneous velocity of the shuttlecock when it hits the ground is
[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]
From the question we are told
Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the
shuttlecock when it hits the ground? Show your work below.
Generally the equation for acceleration is mathematically given as
[tex]a=v \frac{dv}{dx}\\\\\Therefore\\\\\2ah=v^2-u^2[/tex]
Where
acceleration is still -9.81 m/s2,
Hence,
[tex]V^2-U^2=2(-9.81)*-H[/tex]
Therefore
[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]

A student pushes a chair into a desk. If the student's push is the action force, then what is the reaction force in this example of Newton's third law?
A. the force that the chair exerts on the desk after it is pushed in
B. the force of friction acting on the chair
C. the force of gravity acting on the chair
D. the force from the chair on the student
Answer:
Ans : C
Explanation:
C. The force of gravity acting on the chair
Answer:
D. the force from the chair on the student
Explanation:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

will an object have the same weight on moon as it does ?
Answer:
The mass of an object is the same everywhere either on earth or moon.
The weight of an object depends on a gravitational acceleration and it's different from one on earth and that on moon.
therefore the weight changes but the mass is the same.
