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!​

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

Explanation:

The formula for centripetal acceleration is:

, 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:

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

Hope this helped!

Option (C) is correct.

Explanation:

Assuming that the hiker starts walking from the origin O as shown in the figure.

First, he walks 200 m west to point A (say), then he walks 100 m north to the final point B (say) as shown in the figure.

The final point B is in the north-west direction, therefore, the resulting point is in the north-west direction.

Hence, option (C) is correct.
