Kinematics Question 224

Question: A body, thrown upwards with some velocity, reaches the maximum height of 20m. Another body with double the mass thrown up, with double initial velocity will reach a maximum height of [KCET 2001]

Options:

A) 200 m

B) 16 m

C) 80 m

D) 40 m

Show Answer

Answer:

Correct Answer: C

Solution:

Mass does not affect on maximum height. H=u22gHu2 , So if velocity is doubled then height will become four times. i.e. H=20×4=80m
