Homework Statement 1.express the volume in terms of the diameter d of the sphere 2.write an equation to find the density of the sphere in terms of mass M and diameter d Homework Equations sphere Volume = 4 x pi x r^3 / 3 density = mass/volume The Attempt at a Solution 1. d=2r...

if it is traveling horizontally = there is no vertical velocity. that is what I know. am I right? vertical V equation is Vy = Vyi + gravity x delta times so 0 = Vi x sin37 + (-32) x delta times = approximately 15 ft/s^2 + (-32) x delta times so that delta times is 15/32 sec and...

hm.. why do we have to use the vertical velocity? so whicn mean Vy= Vyi - gt ? that what should I do? since there is no displacement to X axis, I am not able to find delta time. I am wondering if you understood this problem. since I wrote whole question from the book thank you !

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...
