A 110-kg man lowers himself to the ground from a height of 12 m by holding on to a rope passed over a frictionless pulley and attached to a 74-kg sandbag. (a) With what speed does the man hit the ground? (b) Is there anything he could do to reduce the speed with which he hits the ground?
Therefore the acceleration with which the man falls is 1.91 m/s2.Therefore the speed of the man with which he hits the ground is 6.77 m/s .Therefore, if the mass of the sandbag is increased, the man can reduce his acceleration followed by his speed with which he hits the ground.It is important to understand that the final speed and acceleration are also dependent on certain variables but those variables are not subjected to changes.
