JEE PYQ: Motion In Two Dimensions Question 6
Question 6 - 2021 (26 Feb Shift 1)
A boy pushes a box of mass 2 kg with a force $\vec{F} = (20\hat{i} + 10\hat{j})$ N on a frictionless surface. If the box was initially at rest, then ________ m is displacement along the $x$-axis after 10 s.
Show Answer
Answer: 500
Solution
$a_x = 20/2 = 10$ m/s$^2$. $S_x = \frac{1}{2}(10)(10)^2 = 500$ m.
