Question

A block of mass m = 1 kg is sliding on a horizontal surface with initial velocity vo = 2 m/s. The block
is brought to a stop by kinetic friction in a distance of 4 m. What is the work done by the force of
friction acting on the block?
-2 J
-8 J
2J
8 J
-0.5 J
0.5 J

Expert Solution

Step 1

Solution:

Given:

m = mass of block = 1 kg

v₀ = speed of block = 2 $\frac{m}{s}$

s = distance in which block is brought to stop by kinetic friction = 4 m

U3 = work done by the force of friction on the block = ?

We will find the answer using the standard formula.
