In a game. A coin of mass 5 grams is struck and slides across a wooden board.

If the co-efficient of friction of 0.4 and the coin is struck with a speed of 1.5m/s.

How far will it slide until it comes to rest?

I got this far... And now i'm stuck...(image attached)

Limiting friction = 0.05g * 0.4 = 0196N.

D - 0.196N = 0.05a

Well i have that u = 1.5m/s and v = 0...however i need acceleration in order to use any of the equations to find the distance..and I'm not sure how to do it...

Thank-you :)
