Answers is  F=7.84 N

Friction force resists the effect of horizontal force and trying to approch to a limiting force.

we have formula for limiting friction force between block and floor

               F=Ц N

where N=mg

putting values we get answer.

The equation for gravity is given by:

F_G =  \frac{G m_1 m_2}{r^2}

1. If r goes up by a factor of 3, gravity goes down by a factor of 9.
2. If m₁*m₂ goes up by a factor of 24, gravity goes up by a factor of 24.

a 0.60 kg ball is moving horizontally with a speed of 5.7 m/s when it strikes a vertical wall. the ball rebounds with a speed of
elixir [45]

We can use the following equation to solve this problem:

<h3>Δp=m∣Vi−Vf∣</h3>

(Where p is the momentum change, m is mass, Vi is initial velocity, and

Vf is final velocity)

Substitute the values given to us in the question:

Δp=(0.6)∣(5.7−(−2.7)∣

Δp=4.9 kg.m/s

Final answer: 4.9kg.m/s.

The change in momentum (Δp) is defined as the change in the mass times the velocity of an object. A force is required to change the momentum of an object. This applied force can increase or decrease momentum, or even change the orientation of an object.

newtons 3rd law of motion states that "every action has an equal and oppisite reaction" A golf ball was hit with a force of 200
jolli1 [7]
This relates to newtons law of motion because that golf ball hit so hard that it went the same speed. because its force the more u like hit it your gonna get that force.
hope this makes sense

A squirrel on a limb near the top of a tree loses its grip on a nut, so that the nut slips away horizontally at a speed of 1.5m/
tatiyna

Answer:

The height of the squirrel  h =113 \  m

Explanation:

From the question we are told that  

    The horizontally speed is v  = 1.5 m/s

    The horizontal  distance d =  7.2 \ m

Generally the the time taken is mathematically represented

      t = \frac{d}{v}

=>   t = \frac{7.2}{1.5}

=>   t = 4.8 \  s

Generally from kinematic equation we have that

     h =  ut + \frac{1}{2} gt^2

Here u  is the initial velocity of nut in the vertical and the value is 0 m/s

     h =  0 * 4.8  + \frac{1}{2} * 9.8 * (4.8)^2

=>  h =113 \  m
