| At some point in time, the parachutist began to descend uniformly at a speed of 5 m / s. Moving at such a speed, after 4 minutes he reached the ground. What path did the parachutist overcome during this time?
V = 5 m / s.
t = 4 min = 240 s.
S -?
The forces that act on the parachutist balance each other, so he moves in a uniform straight line.
With uniform rectilinear movement, the path S traversed by the body is determined by the product of the speed of movement V and the time of movement t: S = V * t.
S = 5 m / s * 240 s = 1200 m.
Answer: the parachutist covered the path S = 1200 m.
