During first half of a journey by a body it travel with a speed of 40km/hr and in the next half it travels with a speed of 20 km

Zanzabum

Answer:

Average speed = 26.67 km/h

Explanation:

It is given that,

The first half of the journey by a body is traveled with a speed of 40 km/h and the next half is covered with a speed of 20 km/h

We need to find the average speed of the whole journey. When two speeds are given, the average speed is given by :

$v=\dfrac{2v_1v_2}{v_1+v_2}\\\\v=\dfrac{2\times 40\times 20}{40+20}\\\\v=26.67\ km/h$

So, the average speed of the body of the whole journey is 26.67 km/h.

DochEvi [55]

Answer:

Explanation:

The Law of Momentum Conservation for us has the equation

$[m_rv_r+m_gv_g]_b=[m_rv_r+m_gv_g]_a$ and filling in:

$[(.50)(5.0)+(.50)(0)]=[(.50)(2.0)+(.50)v_g]$ and

2.5 = 1.0 + .50v and

1.5 = .50v so

v = 3 m/s
