ANSWER:
Step 1 of 5
Our aim is to find the coefficient of the kinetic friction \(\left(\mu_{k}\right)\) between the block and the smooth metal using the given data. We have to plot the graph and find it.
The mass of the block \(\mathrm{m}=350 \mathrm{~g}=0.35 \mathrm{~kg}\)
The acceleration due to gravity \(g=9.8 \mathrm{~m} / \mathrm{s}^{2}\)
