Question

Suppose that a toy car moving at 7.20 m/s is going around a track that has a radius of 1.50 m. What acceleration will the car experience at that speed?
Question 4 options:

a)

4.80 m/s²

b)

10.8 m/s²

c)

34.56 m/s²

d)

0.208 m/s²

Answer 1

Answer:

$a=34.56\ m/s^2$

Step-by-step explanation:

Given that,

Speed of a toy car, v = 7.2 m/s

Radius of the circular track, v = 1.5 m

We need to find the acceleration of the car. When an object moves in a circular path, it will have centripetal acceleration. It can be given as follows :

$a=\dfrac{v^2}{r}\\\\a=\dfrac{(7.2)^2}{1.5}\\\\=34.56\ m/s^2$

So, the centripetal acceleration of the toy car is $34.56\ m/s^2$. Hence, the correct option is (c).
