It's also possible to first find the x- and y-components vfx and vfy of the resultant velocity. the magnitude and direction of the resultant velocity can then be found with the pythagorean theorem, vf = √vfx2 + vfy2, and the inverse tangent function θ = tan-1 (vfy/vfx). setting up this alternate approach is a simple matter of substituting vfx = vf cos θ and vfy = vf sin θ in equations (1) and (2). question if the car and van had identical mass and speed, what would the resultant angle have been?

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
