## Homework Statement

a ball is projected at an angle of 37degree with respect to the horizontal with an initial speed of 25ft/s. if it is traveling horizontally when it hits a verical wall,

what is the height of the wall?

## Homework Equations

## The Attempt at a Solution

a) Vxi = 25 x cos37 = approximately 20ft/s , Vyi = 15 x sin37 = app 15ft/s

height of wall = Y axis displacement

so delta Y = Vyi x delta time + 1/2 x gravity x delta time^2

there is no information about displacement to X axis

in this case how can I get delta time?
