Un carro de juguete da vueltas en una pista circular de 45 cm de diametro si emplea 0,5 s en realizar una vuelta dteemina

Answers:

The complete question in english is written below:

A toy car spins on a circular track 45 cm in diameter. If it uses 0.5 seconds to make a complete circle, determine:

a- period and frequency in one circle

b-the distance it travels around the circular path

c-linear velocity

d-angular velocity

e-centripetal acceleration

a- period and frequency in one circle

According to the given information the period is and since the frequency is the inverse of the period, we have:

b-the distance it travels around the circular path

Here we have to calculate the perimeter of the circular path:

Where is the diameter

c-linear velocity

We can calculate the linear velocity by:

d-angular velocity

Angular velocity is given by:

e-centripetal acceleration

Centripetal acceleration is given by:

in the 1800s, locomotives powered by steam made transportation faster and cheaper. the resulting rapid growth of railroads led to the connection of the atlantic and pacific railroad in oklahoma city in 1897.

in the last years of the century, the improvement of steam-based engines the expansion and growth of railroads. this growth increased when the companies started to build and expand, such as the atlantic and pacific railroad, which connected new mexico with california, and missouri with oklahoma. many of these new networks were built in oklahoma, and these changes transportation henceforward.
