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:
