The load falls freely without initial speed from a certain height. How many times will its final speed increase if the initial height is doubled?
The shortest solution to this problem is obtained if we apply the formula connecting the indicated kinematic quantities without using the “time” value. Having received the dependence of the final speed on the height, we substitute the height 2 times greater into this formula. We see that the final speed will increase by the square root of 2 times.
