What is the relationship between Newton's first law of motion and inertia?

1 answer:

4 0

Explanation: Newton's first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion.

Mariulka [41]

Earthquake S - Waves are examples of transverse waves. The correct option among all the options that are given in the question is the second option. Other good examples of transverse waves are an oscillating string and light waves. A wave is a kind of disturbance that or an oscillation that travels through space.

UkoKoshka [18]

Answer:

The height is 3.1m

Explanation:

Here we have a conservation of energy problem, we have a conversion form eslastic potencial energy to gravitational potencial energy, so:

$E_e=\frac{1}{2}K*x^2\\E_e=\frac{1}{2}18N/m*(9.5*10^{-2}m)^2\\E_e=0.081J$

then we have only gravitational potencial energy when the ball is at its maximun height.

$E_g=m*g*h$

because all the energy was transformed Eg=Ee

$h=\frac{0.081J}{9.8m/s^2*m}$

searching the web, the mass of a ping pong ball is 2.7 gr in average. so:

$h=\frac{0.081J}{9.8m/s^2*(2.7*10^{-3}kg)}\\h=3.1m$

Suppose that you are standing on a train accelerating at 0.20g. What minimum coefficient of static friction must exist between y

Ilia_Sergeevich [38]

Acceleration = (0.2 x g) = 1.96m/sec^2.
Accelerating force on 1kg. = (ma) = 1.96N. 
1kg. has a weight (normal force) of 9.8N. 
Coefficient µ = 1.96/9.8 = 0.2 minimum. 

Coefficient is a ratio, so holds true for any value of mass to find accelerating force acting. 
e.g. 75kg = (75 x g) = 735N. 
Accelerating force = (735 x 0.2) = 147N

Answer:

1531 m

Explanation:

The motion of the jet ski is an uniformly accelerated motion, so we can find the distance travelled by using the following suvat equation:

$s=ut+\frac{1}{2}at^2$
