When an object moves eastward at a speed of 5 m / s for 6 m / s, and northward at a speed of 3 M / s for 4 S, the velocity of the object in the 10 s is the same What is the average speed.

S1=5×6=30m
S2=3×4=12m
S=√（30²+12²）=32.31m
Average velocity v = s / T = 32.31/10 = 3.231m/s

Why is it that when the rope is stretched straight and breaks suddenly, the tension of the rope will disappear instantly, while when both sides of the spring are stretched with the rope (or compressed with other methods), when the rope is broken, or when other parts are relaxed, the elasticity of the spring will not disappear instantly?

15. About springs, rubber ropes and ropes! Isn't the tension constant at the moment when the spring and the rubber rope break? For example, when the rope and the spring are used to bolt a heavy object and a wooden pole respectively, the tension of the spring on it doesn't change at the moment when it is cut? Here is a question that is a little incomprehensible: "in children's bungee jumping," the elastic rubber rope tied to the left and right sides of the waist is excellent, The tension of the two rubber ropes is just Mg (that is, the angle between the two of the three ropes is 120 degrees). The moment when the rubber rope on Xiaoming's left side breaks () why is the answer: acceleration a = g, the direction is opposite to the original tension direction of the broken rubber rope? The speed keeps the same with the situation. But the analysis of acceleration means that the rubber rope on the left side breaks, and because of the instantaneous invariance of the rubber rope, So the tension of the right rubber rope is constant, so the acceleration is g, which is opposite to the original tension direction of the broken rubber rope. My idea is that the left rubber rope should also have instantaneous invariance? Please answer my question comprehensively
