An entrepreneur would like their customers to come back, with this the customer service must be good. The owner’s workers must be kind & fair to the consumers. However good your product or service is, the simple truth is that no-one will buy it if they don't want it or believe they don't need it. And you won't persuade anyone that they want or need to buy what you're offering unless you clearly understand what it is your customers really want.

Knowing and understanding customer needs is at the centre of every successful business, whether it sells directly to individuals or other businesses. Once you have this knowledge, you can use it to persuade potential and existing customers that buying from you is in their best interests.

This guide tells you what you need to know about your customers, how to use this information to sell to them more effectively, and how to win business from your competitors.

(a) How fast must a 3000-kg elephant move to have the same kinetic energy as a 65.0-kg sprinter running at 10.0 m/ s?
Aleksandr-060686 [28]

Answer:

1.4719 m per sec

Explanation:

Hello

Kinetic energy is the energy associated with the movement of objects. Although there are many forms of kinetic energy  

the formula to use is

E=\frac{mv^{2} }{2}

where m is the mass of the object and v the velocity

lets see the kinetic energy of the sprinter running

E=\frac{65 Kg*10(\frac{m}{s} ^)){2} }{2} \\\\E=\frac{65 *100 }{2} \\E=3250 Joules\\\\

Now, the elephant must have the same kinetic energy

E=\frac{m*v_{2} ^{2} }{2} \\\\E*2=m*v_{2} ^{2}\\ \frac{2E}{m} =v_{2} ^{2} \\\sqrt{\frac{2E}{m} } =v_{2}  \\\\\\v_{2} =\sqrt{\frac{2*3250}{3000} }\\ \\v_{2} =1.4719 \frac{m}{s} \\\\

it works only the positive root, so the elephant must to  walk  to 1.4719 m/s to have the same kinetic energy.

Have a great day

Calculate the work done by a person who exerts a force of 200.0 N in the horizontal direction on a box that moves 10.0 meters al
Westkost [7]

Answer:

the work done by a person is 1,732 J

Explanation:

The computation of the work done by a person is as follows;

The following information is given

Force = 200.N

Distance = 10.0 meters

Angle = 30 degrees

based on the above information

Work done is

\overset{F}{\rightarrow}. \overset{D}{\rightarrow}\\\\fd cos \theta

Work done is

= (200) (cos 30 degrees)  (10.0 meters)

= 1,732 J

hence, the work done by a person is 1,732 J

The same is considered and relevant
