A block is projected with a speed of 3.0 m/s on a horizontal surface. if the block comes to rest in 1.5 m, what is the coefficient of kinetic friction between the block and the surface?
I'm not really sure which equations to use for this problem since there is no mass given for the block.
The Attempt at a Solution
I really have no idea how to go about doing this problem!
I've been solving more complex friction problems but I'm currently baffled since there is no way to calculate a force, etc.
I'm taking a 12th grade physics class, by the way.
