Ametal marble is launched with a speed of v0 = 3.1 m/s at 35° relative to the horizontal, from a height of 1.1 m above ground, and towards a very tall vertical wall, which is 1.6 m away from the launch position. the projectile may first hit the wall, or the ground. find: (a) the highest point (both the x- and the y-coordinates) that the projectile reaches between its launch and the collision; (b) the location of the collision (both the x-and the y-coordinates); (c) the velocity (the magnitude and the angle relative to the horizontal -make a sketch so that it is clear which angle you are reporting) at the moment of the collision. same question, but now assume that the vertical wall is 1.8 m away from the launch position

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
