A pumpkin was rolling down a hill that is 12.3 miles long from top to bottom. The pumpkin achieved a final velocity of 42.4 m/s and it took 3.5 minutes to roll down the hill The pumpkin had a mass of 4780 grams. What momentum AND force did the pumpkin have at the
bottom of the hill?

120v is the answer i am positive tell me if this was correct

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.

Because its not moving at that time hope u understand
