Calculate tension(centripetal force) of the rope with a stone at its end. Mass of the stone is $2\mathrm{kg}$, length of the rope is $5\mathrm{m}$, the stone velocity is $10\mathrm{m}/2$

Solution:

$\mathrm{m} = 2\mathrm{kg}$ – mass of the stone;

$l = 5\mathrm{m}$ – length of the rope;

$V = 10\frac{\mathrm{m}}{\mathrm{s}}$

Formula for the centripetal force:

$$F = m a _ {c} = m \frac {V ^ {2}}{l} = 2 k g \cdot \frac {\left(1 0 \frac {m}{s}\right) ^ {2}}{5 m} = 4 0 N$$

Answer: centripetal force of the rope is equal to 40N.
