Body falls vertically. Its initial speed is zero and its fall duration is 2 min. The mass of the body is m=80 kgr. The air friction force is opposite to the velocity of the body with a factor of R=60 Nt s/m. Given g=10m/s². A) Draw the vertical z-axis with any direction you want and write the equation of motion of the body. B) To find the speed of the body as a function of time. C) With what speed does the body reach the ground?
