Final answer:
The correct expression to find the velocity of an object hitting the ground from a height h is derived from the kinematic equation v = √(2gh).
Step-by-step explanation:
The question pertains to the velocity an object acquires when dropped from a height above the ground in the context of physics. The equation given, 4.41 h, seems to imply that the velocity of the object hitting the ground can be directly calculated from the height it is dropped from. However, the standard kinematic equation for an object in free fall without air resistance is v = √(2gh), where g is the acceleration due to gravity (9.8 m/s²) and h is the height in meters. Therefore, the given expression is not accurate according to standard physics equations. For a correct analysis, we would use the mentioned kinematic equation which results from the conservation of energy or the equations of motion under constant acceleration.
The equation to calculate the velocity of an object as it hits the ground when dropped from a height h is given as 4.41h. This equation assumes that there is no air resistance acting on the object. The velocity is directly proportional to the height, so as the height increases, the velocity also increases.
