A block of mass $1 kg$ starts from rest at $x = 0$ and moves along the $X$ -axis under the action of a force $F = k t,$ where $t$ is time and $k = 1 Ns^{- 1}$ . The distance the block will trave] in 6 seconds is

Answer:

Solution:

From Newton's second law $F = ma m = 1 kg F = 1 \times a = \frac{d v}{d t}$ According to the question, $F = k t = \frac{d v}{d t}$ $d v = k t \cdot d t$ Integration gives $v x = \frac{k t ^{2}}{2} = \frac{d x}{d t} = \frac{k t ^{3}}{6} = \frac{1 \times 6 \times 6 \times 6}{6} = 36 m$
