fall to the ground.
A. What is the speed of the ball just before it reaches Henry?
B. What is the speed of the ball just before it reaches the ground?

- All parts needed for like otherwise dislikearrow_forwardAn object is released from rest at a height of h. During the final second of its fall, it traverses a distance of 38m. Determine h. I would like to know the solution but also maybe an explanation on how I would know what process to take. For the last second, I was able to find that final vf = 38m/s. That is vf = deltax/deltat, or 38m/1s. I plugged it in to vf2 = vo2 + 2a(deltax), since I think that vf shouldn't change for h, but I got the wrong answer. Please explain.arrow_forwardA skier gliding across the snow at 3.0 m/s suddenly starts down a 10° incline, reaching a speed of 15 m/s at the bottom.
