Questions: In South's CSL Championship game, Ray - South's 80.0-kg tight end - was moving with a speed of 5.58 m / s when he collided mid-air near the goal line with an opposing player. If Ray experiences a force of 920 N over a time period of 0.284 s, then determine Ray's momentum change. (No or - signs.) Momentum Change kg ⋅ m / s

Solution Steps

We need to determine the change in momentum experienced by Ray during the collision. The change in momentum (\(\Delta p\)) can be calculated using the impulse-momentum theorem, which states that the impulse experienced by an object is equal to the change in its momentum.

The impulse-momentum theorem is given by:

\[ \Delta p = F \cdot \Delta t \]

where:

• \( F \) is the force applied (920 N),
• \( \Delta t \) is the time duration of the force (0.284 s).

Substitute the given values into the impulse-momentum theorem:

\[ \Delta p = 920 \, \text{N} \times 0.284 \, \text{s} \]

\[ \Delta p = 261.28 \, \text{kg} \cdot \text{m/s} \]
