If, with uniform rectilinear movement, the body moves 120 m in 1 minute, then in 10 seconds

If, with uniform rectilinear movement, the body moves 120 m in 1 minute, then in 10 seconds it will move to … in 5 seconds it will move to …

Given:

t = 1 minute = 60 seconds – the time interval during which the body travels a path equal to L;

L = 120 meters – section of the path;

t1 = 10 seconds – time interval;

t2 = 5 seconds – time span.

It is required to determine L1 and L2 (meter) – how much the body will move over the time intervals t1 and t2, respectively.

Let’s determine the speed of the body:

v = L / t = 120/60 = 12/6 = 2 m / s (meters per second).

Then, during the time interval t1, the body will cover the path:

L1 = v * t1 = 2 * 10 = 20 meters.

During the time interval t2, the body will cover the path:

L2 = t2 * v = 5 * 2 = 10 meters.

Answer: in 10 seconds the body will move 20 meters, in 5 seconds – 10 meters.
