Algebra.Com's Answer #817464 by Alan3354(69443) You can put this solution on YOUR website! John is on top of the building and Jack is down. If John throws ball at an angle of 60° and with initial velocity 20m/s at what height will the ball reach after 2s? Consider the motion along the y direction. Show your solution. (The height of the building was not given) \n" ); document.write( "--------------- \n" ); document.write( "You didn't spec the acceleration due to gravity. I'll use 10 m/sec/sec \n" ); document.write( "--- \n" ); document.write( "h(t) = -5t^2 + 20t*sin(60) \n" ); document.write( "Sub 2 for t, do the arithmetic.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
