Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
a ball is dropped from a building and simultaneously another ball is projected upward with some velocity.describe the change in relative velocities of the ball as a function of time (IIT JEE) drops of water fall at regular intervals from the roof of a building of height 16m. the first drop strikes the ground at the same moment as the fifth drop leaves the roof . find the distance between the 2 nd and 3 rd drops. (AIEEE-2007) a ball is dropped from a building and simultaneously another ball is projected upward with some velocity.describe the change in relative velocities of the ball as a function of time (IIT JEE) drops of water fall at regular intervals from the roof of a building of height 16m. the first drop strikes the ground at the same moment as the fifth drop leaves the roof . find the distance between the 2nd and 3rd drops.

If you know the basics then you can solve it Remember that there are 4 drops in air simultaneously So take ratio like 1x+3x+5x+7x= 16I.e. X=1 Distance between 2nd and 3rd drop is 5-3 = 2m
