The instantaneous angular acceleration is given by the formula:
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Explanation: The instantaneous angular acceleration is the time derivative of angular velocity α=limΔt→0Δω/Δt=dωdt α = lim Δ t → 0 Δ ω/ Δ t = d ω /d t . The angular acceleration →α is found by locating the angular velocity.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
