Answer #1

Thank you. The upward force is of 20N and downward force due to gravity on 2 Kg rock is 20N. So the net force is 0 on the rock. So it moves at constant velocity. Please like the answer ASAP

    Calculate the terminal velocity for a pollen grain falling through the air using the drag force equation. Assume the pollen grain has a diameter of 7 µm and a density of 0.3 g/cm3. If this grain is released from the top of a tree (height 11 m), estimate the time it will take to fall to the ground. Hint: The pollen grain will reach its terminal velocity very quickly and will have this velocity for essentially the entire motion. Your...
