03. AAMrelsarticle starts from rest with constant acceleration. Ita distance x in the first 10 s and a distance y in the next 20 s. Theion between x and y is (a) y x (b) y2x (c) y 8x (d) y-4x. 04. |

Answer» distance covered in 1st 10sec => x= 1/2*(a)*(10)² = 50a speed after 10sec => v = 10a so, y = 10a*(20) +1/2*(a)*(20)² =200a+200a = 400a so, here y/x = 400a/50a = 8 y = 8x option c |
