Question

A physics book slides off a horizontal table top with a velocity of 1.25 m/s. It strikes the floor in .4 s. What is the height of the table and the landing position of the book?

Answer 1

Let the height of the table be `h` then
`h=1/2xxgxxt^2`
`=>h=1/2xx10xx (0.4)^2`
`:.h=0.8m`
Also the horizontal displacement of the book can be given by `d=1.25xx0.4=0.5 m`
