A particle covers half of its total distance with speed

v1 and the rest half distance with speed v2. Its average

speed during the complete journey is

• V_{1 +} V₂ / 2

• V₁ V₂ /V_{1 +} V₂

• 2V₁ V₂ /V_{1 +} V₂

• V²₁ V²₂ /V²_{1 +} V²₂

The displacement ‘x’ (in meter) of a particle of

mass ‘m’ (in kg) moving in one dimension under

the action of a force, is related to time ‘t’ (in sec) by

t= √x̅+̅3̅. The displacement of the particle when its

velocity is zero, will be

• 4 m

• 0 m

• 6 m

• 2 m
