Can cars stop on a dime? calculate the acceleration of a 1400 kg car if it can stop from 35 km/h on a dime (diameter= 1.7 cm) how many g’s is this?

The acceleration of the cart is 283.54g

Explanation:

It is given that,

Initial speed of the car, u = 35 km/h = 9.72 m/s

Finally, it stops, v = 0

Diameter of the dime, d = 1.7 cm

Let a is the acceleration of the car. Using third equation of motion to find it as :

So, the acceleration of the car is and it is decelerating.

Since,

So,

So, the acceleration of the cart is 283.54g. Hence, this is the required solution.

i think its c if i'm wrong
