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?
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?
