Question

A 1300 kg car traveling with a speed of 3.5 m/s executes a turn with a 8.5 m radius of curvature.

Calculate the centripetal acceleration of the car.
I need the answer please help!​

Answer 1

1.4 m/s/s (2.s.f)

Step-by-step explanation:

The formula for centripetal acceleration is:

`a=(v^(2) )/(r)`, where v is velocity and r is the radius.

In the question we are given the information that the car has a mass of 1300kg, a velocity of 2.5m/s, and a turn radius of 8.5m which are all the values we need. Therefore we can simply substitute in the values to solve the question:

`a=(3.5^(2) )/(8.5) \\a=1.4`

Therefore the centripetal acceleration of the car is 1.4m/s/s. (2.s.f)

Hope this helped!
