Hi, I was wondering if anyone could help me with this question?
A dump truck filled with pumpkins is travelling at 20 m/s when a pumpkin falls off the back and onto
the road, 5 m below. When the pumpkin hits the road, it will be
A) 5 m behind the truck.
B) 20 m behind the truck.
C) 40 m behind the truck.
D) less than 1 m behind the truck.
I used the equation d=(1/2)at^2 to find the time that it took the pumpkin to fall 5m. Then, I assumed that the horizontal velocity of the pumpkin is 20 m/s, so after finding time, I used V=d/t, 20=d/1. I found that the pumpkin should be 20m behind the truck, but the solution to this question is D.
Can anyone tell me why?
Thanks a bunch.
