<h3>answer</h3>

A locomotive engine with a mad of 205000kg moving with 5m/s

Explanation:

from \: the \: options \: substitute \: the \: formulars \: for \: kinetic \: energy \\ for \: opton \: a \: ke =  \frac{1}{2} mv {}^{2}  =  \frac{1}{2} \times 3500 \times 30 {}^{2}   = 1575000 \\ for \: option \: b \: ke =  \frac{1}{2} mv {}^{2} =  \frac{1}{2} \times   73 \times 6 {}^{2}  = 1314 \\ for \: option \:  \: c =  \frac{1}{2}mv {}^{2}  =  \frac{1}{2}  \times 205000 \times 5 {}^{2}  = 2562500 \\ for \: option \: d \:  =  \frac{1}{2}mv {}^{2} =  \frac{1}{2} \times 0.5 \times(46.9) {}^{2}   = 549.9025  \\ from \: the \: analysis \: above \: the \: options \: that \: has \: the \: highest \: kinetic \: energy \: is \: a \: locomotive \: engine \: with \: a \: mass \: of \: 205000kg \: moving \: with \: a \: velocity \: of \: 5 \frac{m}{s}

Aliun [14]

Answer:570.54 N

Explanation:

Given

mass of man=76 kg

\theta =50^{\circ}

As man is standing over inclined building therefore

its weight has two components i.e. sin and cos component

Force perpendicular to inclined wall

F=mgcos\theta =76\times 9.8\times \sin 50

F=570.54 N

One object is thrown vertically upward with an initial velocity of 100 m/s and
gavmur [86]

We have that for the Question it can be said that The maximum height reached  by the first <em>object</em> will be  100 times  that of the other.

  • (H_{max})_1=100*(H_{max})_2

From the question we are told

One object is thrown vertically upward with an initial velocity of 100 m/s and  another object with an initial velocity of 10 m/s. The maximum height reached  by the first object will be

that of the other.

a. 10,000 times

b. none of these

<em>c. </em><em>1000 times</em>

d. 100 times

<em>e.</em><em> 10 times</em>

Generally the equation for the velocity is mathematically given as

v=\frac{d}{t}\\\\Where\\\\\frac{H_{max}_1}{H_{max}_2}=\frac{(V_1)^2}{(v_2)^2}\\\\\frac{H_{max}_1}{H_{max}_2}=\frac{10000}{(10}\\\\

(H_{max})_1=100*(H_{max})_2

Therefore

The maximum height reached  by the first <em>object</em> will be  100 times  that of the other.

(H_{max})_1=100*(H_{max})_2

Alexus [3.1K]
It is true that there are two types of addiction, psychological and physical. When it comes to physical addiction, it normally refers to drug withdrawal or drug usage, when your body is exhibiting various symptoms of needing drugs. Mental addiction refers to when there is no actual need to use the object of addiction, but rather a mental desire to use it and have it again.
