Aball is thrown eastward into the air from the origin (in the direction of the positive x-axis). the initial velocity is 40 i + 32 k, with speed measured in feet per second. the spin of the ball results in a southward acceleration of 6 ft/s2, so the acceleration vector is a = −6 j − 32 k. where does the ball land? (round your answers to one decimal place.) ft from the origin at an angle of ° from the eastern direction toward the south. with what speed does the ball hit the ground? (round your answer to one decimal place.) ft/s

Iwould say a is accurate

Sorry i don’t know what to do

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.
