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

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 :

So, the centripetal acceleration of the toy car is . Hence, the correct option is (c).

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
