A body starts from rest and accelerates uniformly at 2 m per second squared for 5 seconds. Its final velocity is:

1. Use the first equation of uniformly accelerated motion: v = u + at. 2. Given u = 0 (starts from rest), a = 2 m per second squared, t = 5 s. 3. Substitute: v = 0 + 2 × 5. 4. v = 10 m per second. 5. Option D mistakes the formula for s = ½at² and computes displacement instead. _Source: Selina Concise Physics ICSE Class 9, Ch 2 'Motion in One Dimension' (aplustopper.com extract)_
