Which law of motion describes squeal and oppisit forces of action and reaction

1 answer:

4 0

These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

Hope this helps! :)

A 7 kg ball is moving at a constant speed of 5 m/s. A force of 300 N is applied to the ball for 4 s. The new speed of the ball i

olasank [31]

Answer:

The new speed of the ball is 176.43 m/s

Explanation:

Given;

mass of the ball, m = 7 kg

initial speed of the ball, u = 5 m/s

applied force, F = 300 N

time of force action on the ball, t = 4 s

Apply Newton's second law of motion;

$F = ma = \frac{m(v-u)}{t}\\\\m(v-u) = Ft\\\\v-u = \frac{Ft}{m}\\\\v = \frac{Ft}{m} + u$

where;

v is new speed of the ball

$v = \frac{Ft}{m} + u\\\\v =\frac{300*4}{7} + 5\\\\v = 176.43 \ m/s$

Therefore, the new speed of the ball is 176.43 m/s

A 73-kg Norwegian olympian ski champion is going down a hill sloped at 39 ◦ . The coefficient of kinetic friction between the sk

bazaltina [42]

Answer:

Explanation:

net force on the skier = mg sin 39 - μ mg cos39

mg ( sin39 - μ cos39 )

= 73 x 9.8 ( .629 - .116)

= 367 N

impulse = net force x time = change in momentum .

= 367 x 5 = 1835 kg m /s

velocity of the skier after 5 s = 1835 / 73

= 25.13 m /s

b )

net force becomes zero

mg ( sin39 - μ cos39 ) = 0

μ = tan39

= .81

c )

net force becomes zero , so he will continue to go ahead with constant speed of 25.13 m /s

so he will have speed of 25.13 m /s after 5 s .

A car increases its speed from 4.20 m/s to 8.60 m/s over 3.20 seconds. What is the car’s acceleration?

katrin2010 [14]

Answer:1.375metre per second square

Explanation: acceleration=(final velocity-initial velocity)÷time

acceleration=(8.6-4.2)÷3.2

Acceleration=4.4÷3.2

Acceleration=1.375 metre per second square

I. How does The Bhutan Forest Act of 1969, affect the lives of shifting cultivators?

ZanzabumX [31]

The Bhutan Forest Act of 1969, affect the lives of shifting cultivators because the act placed the status of Tsheri land on the same footing with wetland and rain-fed land.

<h3>What is shifting cultivators?</h3>

A field that had been developed whenever was left neglected for quite a long time, Shifting cultivators were tracked down in the sloping and forested lots of North-east and Central India. The existences of these ancestral individuals relied upon free development inside backwoods and on having the option to involve the land and woods for developing their harvests.

The Forest Act of 1969 has restricted new clearances for moving development however has not deterred the act of it where such development doesn't jeopardize the wellbeing of the roadway and public property. The Land Act of 1979 has put the situation with
Tsheri land on a similar footing with wetland and rain fed land.

Thus, Bhutan Forest Act of 1969, affect the lives of shifting cultivators.
