A particle starts with velocity m/s and moves with a constant acceleration of m/s. Find its velocity after s.
Answer and explanation
Correct answer: A. 25 m/s
- Step 1: Integrate the acceleration: , and at , so . Step 2. At : m/s. Answer: 25 m/s. Why not the others: 24 m/s: That ignores the initial velocity. 1 m/s: That is the initial velocity only. 11 m/s: That multiplies the initial velocity by 3 instead of the acceleration.
