nursing AIIMS BSc Nursing 2025 Mock Test Series Physics Motion in a Straight Line Average velocity and average speed
A body of mass 'm' moving along a straight line covers half the distance with a speed of 2 ms-1. The remaining half of the distance is covered in two equal time intervals with a speed of 3 ms-1 and 5 ms-1 respectively. The average speed of the particle for the entire journey is
1
\(\frac{8}{3}~m{{s}^{-1}}\)
2
\(\frac{4}{3}~m{{s}^{-1}}\)
3
\(\frac{16}{3}~m{{s}^{-1}}\)
4
\(\frac{3}{8}~m{{s}^{-1}}\)
