A 2.0 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
exis [7]

Answer:

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  

F = \mu mg

F=0.21\times2.0\times9.8

F = 4.12\ N

We need to calculate the acceleration

F = ma

a = \dfrac{F}{m}

a =\dfrac{4.12}{2.0}

a=2.06\ m/s^2

We need to calculate the initial velocity

Using equation of motion

v^2=u^2-2as

Put the value  

0=15^2-2\times2.06\times s

s = \dfrac{15^2}{2\times2.06}

s=54.6\ m

Hence, The distance will be 54.6 m.
