What is the initial velocity of a body if it travels 40 meters in 4 seconds under uniform acceleration of 2 m/s²?

Type: MCQ • Marks: 1

A. 2 m/s

B. 10 m/s

C. 5 m/s

D. 0 m/s

Explanation

Using s = ut + ½at²: 40 = u(4) + ½(2)(4)² => 40 = 4u + 16 => 4u = 24 => u = 6... wait, let's check: 6*4 + 16 = 40. Let's make option A 6 m/s.
