## GR0877 Problem 2

PROBLEM STATEMENT: This problem is still being typed .

SOLUTION: (D) If we ignore friction, horizontal and vertical motions of the object are independent. Therefore, no one really needs the initial horizontal component of the velocity to determine how much it takes to cover some distance in the vertical direction. The initial vertical component of the velocity is zero, so from $H = gt^2/2$ one gets $H = (9.8 \cdot 2^2 )/2 = 9.8 \cdot 2 = 19.6$ (m).
