A2.0 kg wooden block is slid along a concrete surface (μk = 0.21) with an initial speed of 15 m/s. how far will the block slide until it stops?

The distance is 54.6 m

Explanation:

Given that,

Mass = 2.0 kg

Frictional coefficient = 0.21

Initial velocity = 15 m/s

We need to calculate the acceleration

Using formula of frictional force  

We need to calculate the acceleration

We need to calculate the initial velocity

Using equation of motion

Put the value  

Hence, The distance will be 54.6 m.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
