An object moving along -axis with a uniform acceleration has velocity at . After if it is at , then its acceleration is,
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Applying equation of motion in vector form, we get s→=u→t+12a→t2 ⇒-5 i^-3i^=12 i^×2+12×a→×22⇒-8 i^=24 i^+2a→⇒a→=-16 cm s-2 i^
