A ball which is thrown vertically upwards reaches the roof of a house ...
Problem:

A ball is thrown vertically upwards and reaches the roof of a house 100 m high. At the same time, another ball is dropped from rest vertically downwards from the roof of the house. At which height will the balls pass each other? (g = 9.8 m/s^2)


Solution:


  • Let's assume that the ball thrown upwards takes t seconds to reach the roof of the house.

  • Using the equation of motion, we can find the initial velocity of the ball:

  • v=u+at

    0=u-9.8t

    u=9.8t

  • Now we can use another equation of motion to find the height reached by the ball:

  • s=ut+0.5at^2

    100=4.9t^2

    t=4.04 seconds

    Using the same equation of motion, we can find the maximum height reached by the ball:

    s=ut+0.5at^2

    s=9.8(4.04)-0.5(9.8)(4.04)^2

    s=98.04 m

  • Now we can use the same equation of motion to find the time taken by the ball dropped from the roof to reach the ground:

  • s=ut+0.5at^2

    0=0+0.5(9.8)t^2

    t=2 seconds

  • Now we can find the height at which the balls pass each other:

  • Using the equation of motion for the ball thrown upwards:

    s=ut+0.5at^2

    s=9.8(2)+0.5(-9.8)(2)^2

    s=15.6 m

    Therefore, the balls pass each other at a height of 75 m (100 m - 15.6 m).
