A particle is projected vertically upwards with a speed of 16m/s, after some time, when it again passes through the point of projection, its speed is found to be 8m/s. It is found that the work done by air resistance is same during upward and downward motion. Then the maximum height attained by the particle is -
Text Solution
Verified by ExpertsThe correct answer is:
A
From work energy theorem
for upward motion,
m (16) 2 = mgh + W
for downward motion
m (8) 2 = mgh – W
h = 8m
