AP Physics 1 Question (may overlap with AP Physics C:Mechanics) When a ball is launched horizontally with initial speed vo from a height H, the ball lands with speed v after traveling a horizontal distance D. Explain how v and D would be different if a toy airplane with the same mass is launched with the same horizontal speed from the same height, but the toy airplane experiences a small upward lift force from air.
Part A The first active volcano observed outside the Earth was discovered in 1979 on lo, one of the moons of Jupiter. The volcano was observed to be ejecting material to a height of about 3.00 x 10 m. Given that the acceleration of gravity on lo is 1.80 m/s", find the initial velocity of the ejected material.

Same type of track as in the previous problem, this time with d = 2.69 m. The block starts at x = 0, and is given a push to the left with an initial speed of 6.40 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down?
