Answer to Problem 1Q

The horizontal component of an arrow’s velocity is derived from the force applied to the arrow by the bowstring.

Explanation of Solution

Introduction:

According to Newton’s first law, every object continues to be at rest or in the state of uniform motion in a straight line unless an external unbalanced force acts on it.

When an arrow is launched using a bow, the bowstring is pulled, so that energy is stored in it in the form of elastic potential energy. When the string is released, the string exerts a force on the arrow and the arrow gains velocity.

The arrow is initially at rest. The bowstring is pulled and released, keeping the arrow at an angle to the horizontal. If the arrow is launched at an angle, the force exerted on the arrow can be resolved into two components- along the horizontal and the vertical directions. The horizontal component of the force provides the horizontal component of its initial velocity and the vertical component provides the vertical component of its initial velocity. The arrow, thus travels in 2 dimensions, moving both vertically and horizontally.

Conclusion:

Newton’s first law provides an elegant way to explain the two-dimensional motion of the arrow, where the horizontal component of its velocity is provided by the horizontal component of the force exerted on the arrow.
