Answer:

F = m×a  

60 N = 30 kg × a  

30 × a = 60  

a =  60/30  

a =  2 m/s²

 

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

Explanation:

If the net force increases while the mass of the object remains the same, the amount of acceleration also increases.  

However, when the mass of the object increases while the net force remains the same, the amount of acceleration decreases.

F=ma
60=30.a
60/30=30.a/30

A 48.5 kg student runs down the sidewalk and jumps with a horizontal speed of 4.25 m/s onto a stationary skateboard. The student
storchak [24]

<u>Answer:</u>

2.39 kg

<u>Explanation:</u>

There is conservation of momentum here in this problem so we will use the following problem:

m_1u_1+m_2u_2=(m_1+m_2)v

where the mass of the student m_1 is 48.5 kg,

the mass of the skateboard m_2 is m_2 kg,

the initial speed of the student u_1 is 4.25 m/s; and

the speed of the student and skateboard  v is 4.05 m/s.

So substituting the given values in the above formula to get:

(48.5*4.25) + (m_2 * 0) = (48.5 + m_2 ) * 4.05

206.125=196.425+4.05m_2

206.125 - 196.425 = 4.05m_2

m_2=\frac{9.7}{4.05}

m_2=2.39

Therefore, the mass of the skateboard is 2.39 kg.

It is recommended that drinking water contain 1.6 ppm fluoride (F−) for prevention of tooth decay. Consider a reservoir with a d
icang [17]

Answer:

total amount of fluoride 3.6 *10^6 g

Explanation:

we know that

volume of reservoir = \pi r^2 h

                                  =\pi* [\frac{4.70*10^2}{2}]^2 *14.2

                                  = 2.25*10^6 m^3

denso=ity of water = 1000 kg/m3

mass of water = 1000*2.25*10^6

                         = 2.25*10^9 kg = 2.25*10^12 g

fluoride 1.6 ppm

total amount of fluoride = \frac{1.6}{10^6} * 2.25*10^{12} g

                                         = 3.6 *10^6 g
