Drats! That’s not correct.
But you’ll get another chance soon.
Here’s a sketch of the solution:
GIVEN: dy= -AAA m, voy = 0 m/s, ay = -9.8 m/s/s
dx= BBB m, ax = 0 m/s/s
Unknown: vox = ???
Use dy, voy, and ay to find the t (time to fall).
Then use dx and t to find the vox value.
Enter your answer directly into the field OR use our built-in Number Pad.
