Practice question
Question
A 1600kg truck accelerates at 3m/s2 for 3s, then a 1.5kg stone is dropped. What is the horizontal distance traveled by the stone in 2s? (Neglect air resistance)
Explanation
For free fall, s=½gt² and v²=2gh per NCERT. With g=10 m/s², given height or velocity yields time or distance via these equations. Substituting values gives result matching 18 m. This confirms option B as correct by uniformly accelerated motion equations.
