Ahelicopter, initially hovering 404040 feet above the ground, begins to gain altitude at a rate of 212121 feet per second. which of the following functions represents the helicopter’s altitude above the ground yyy, in feet, ttt seconds after the helicopter begins to gain altitude?

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
