Average Velocity

Question

A particle moves a distance of 10 m along a straight line. It covers first 1/3rd of the length of path in 2 second and rest of the length of path with velocity of 1 m/s. Then find its average velocity.

Moderate

A
1.15 m/s
B
2.15 m/s
C
0.92 m/s
D
1.82 m/s

Solution

$v_{a v g} = \frac{D i s p l a c e m e n t}{T i m e} = \frac{10}{(2 + \frac{20}{3 \times 2})} m / s = 1.15 m / s$
