You need to calibrate your giant paint ball bazooka, so you fire it at an angle of 60° and you find that the giant paint ball splatters the ground at a horizontal distance of 107 m from the end of the muzzle, and a distance of 1.7 m below the end of the muzzle. What is the muzzle velocity, vo, of your giant paint ball bazooka,
b. how long does it take for the giant paint ball to hit the ground and splatter,
c. what is the y-component of its velocity just before it splatters,
d. and what is its velocity ... magnitude and
e. direction, just before it splatters.

Letter c i’d say

"induction" is the process of charging an object without touching it.hope my answer has you : )

At maximum height, kinetic energy is converted in potential energy  formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j  so the remaining pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h  = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m 

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3
