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 10s.
Show Hint
Correct Answer: 500
Solution and Explanation
Starting from rest, \(x = \frac{1}{2}a_xt^2 = \frac{1}{2}\times10\times10^2 = 500\) m.
Answer: 500

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
