Megan rolls a ball down a ramp until the ball hits the wall. The ramp is 2. 5 m long and the distance from the end of the ramp to the wall is 1. 5 m. If it took 0. 5 seconds for the ball to hit the wall then what is the ball’s speed?.

answer:

i havent taken the psat, but i have the sat, make sure to bring some snacks, because youre in there forever, 2 sharp number two pencils, an sat approved calculator, and maybe a jacket.   your phone and any books will be taken up, so don't try to bring them(but they will be given back at the end of the testing).   good luck!   i hope you do well!
