Question

a body walks from his home to school along a straight road .he covers distance of 180 meter in 2 minutes to reach the school .after reaching the school the boy finds that school has closed . he intantaneously retarns to his home travelling the same distance in same time .what is the 1)Average speed 2)Average velocity of the body

Answer 1

Answer:

S=180m (going distance)

s=180m (returning distance)

T (while going) =2min=120s

t ( while returning) = 120s

Average speed = (S+s)/(T+t)

= (180×2)/(120×2)

= 360/240

= 3/4

= 0.75 m/s

as the body is traveling in the straight line path so Average speed = Average Velocity.

Average velocity = 0.75 m/s
