A) 100 m
B) 200 m
C) 300 m
D) 400 m
Correct Answer: B
Solution :
Key Idea : At maximum height, final velocity is zero. From equation of motion, we have \[A(x=0)\] where v is final velocity, u is initial velocity, h is height and g is acceleration due to gravity. Since, body reaches maximum height in both cases, hence final velocity is zero. \[C(x=5),\] \[\therefore \] \[y=a\cos (\omega t-kx)\] \[(\omega t-kx)\] Given, \[[k]=\frac{1}{[x]}=\frac{1}{[L]}\] Note: Maximum height attained does not depend upon the mass of the body.You need to login to perform this action.
