MCQ
The unit of angular acceleration in the SI system is
- A$N\,k{g^{ - 1}}$
- B$m\,{s^{ - 2}}$
- ✓$rad\,{s^{ - 2}}$
- D$m\,k{g^{ - 1}}K$
✓
Answer
Correct option: C.
$rad\,{s^{ - 2}}$
c
(c) Angular acceleration $ = \frac{{{\rm{Angular velocity}}}}{{{\rm{Time}}}} = \frac{{rad}}{{{{\sec }^2}}}$
(c) Angular acceleration $ = \frac{{{\rm{Angular velocity}}}}{{{\rm{Time}}}} = \frac{{rad}}{{{{\sec }^2}}}$

→A slide with a frictionless curved surface, which becomes horizontal at its lower end,, is fixed on the terrace of a building of height $3 h$ from the ground, as shown in the figure. A spherical ball of mass $\mathrm{m}$ is released on the slide from rest at a height $h$ from the top of the terrace. The ball leaves the slide with a velocity $\vec{u}_0=u_0 \hat{x}$ and falls on the ground at a distance $d$ from the building making an angle $\theta$ with the horizontal. It bounces off with a velocity $\overrightarrow{\mathrm{v}}$ and reaches a maximum height $h_l$.
