Question

If x is the distance covered in n second and y is the distance covered in nth second ,then​

Answer 1

Answer:

x is equal and greater than y

Answer 2

If x is the distance covered in n second and y is the distance covered in nth second, then​

We can observe distance shrouded in nth second, distance canvassed in nth sec = distance in n sec - distance canvassed in n-1 sec

   

S nth = uₙ +1/2 a n² - { u (n-1) + 1/2 a (n-1)²}

S nth = u + 1/2 a(2n-1)

• This is the formula for distance shrouded in nth second .this is additionally called the fourth condition of motion.
• In basic words assuming that vehicle takes ventures 10m in 2 seconds and 15m in 3sec, so in the third sec it voyages a distance of 15-10=5m.
• I have shown the two induction through which we can infer the formula for distance went in nth second.
