Physics · MOTION IN A STRAIGHT LINE

A body moving with uniform acceleration along a straight path covers a distance of \( 40\text{ m} \) in \( 4\text{ s} \). If its velocity at the end of this interval is \( 15\text{ m s}^{-1} \), what was its initial velocity \( v_0 \)?

1. A
   \( 10\text{ m s}^{-1} \)
2. B
   \( 2.5\text{ m s}^{-1} \)
3. C
   \( 5.0\text{ m s}^{-1} \)
4. D
   \( 7.5\text{ m s}^{-1} \)
