a car moving with the constant velocity of 30m/s comes to rest after 5 seconds. find the acceleration of the car​

The car is traveling East at 30 m/s with respect to the road but is orbiting the center of the Earth at

356.5ms+30ms=385.5ms

The formula for centripetal acceleration is ac=v2r.

So for the car, its centripetal acceleration is

ac=(3.855⋅102ms)26.36⋅106m=14.86⋅1046.36⋅106ms2

ac=v2r

ac=2.34⋅10−2ms2

I hope this helps,

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2
