To find the volume of a triangular prism, you can find the area of the base triangle, and multiply that value by the height of the prism. So let's first find the area of the base triangle (which is its base times height, divided by 2):
Then, multiply this value by the height of the prism, which will give you the prism's volume:
the "acceleration" is -15m/s (it's negative because it is slowing down, not speeding up[it might just be a positive 15m/s if it is called deceleration and not acceleration])
Step-by-step explanation:
30m/s (starting speed)/2 (the number of seconds it took to stop from 30m/s
