40m/s will be reduced to 0m/s in 4 seconds. 4 seconds x 40m/s would be 160m up, but you will only get half of that because you decelerate linearly to 0m/s. This leaves you with 4 x 20 = 80m.
Eric is writing about the cell wall. Chloroplast is for photosynthesis. Mitochondria releases energy from respiration. Nucleus controls the activities of the cell. But the cell wall supports and gives structure to the cell.
