In 10 seconds of uniformly accelerated movement, the body covered a path of 48 m, increasing its speed by 40%. Determine the initial speed of the body.
If the body increased its speed by 40%, then, therefore, in 10 seconds it passed 48 meters at a speed equal to 140% – a new speed.
100% is the initial speed of the body.
New speed: 48 m: 10 sec = 4.8 meters / second
Initial speed = 4.8 m / s: 140 * 100 = (approximately equal) 3.4 m / s
