A Projectile Is Launched at a Height of H Feet $\theta$

question 152

Multiple Choice

A projectile is launched at a height of h feet above the ground at an angle of $\theta$ with the horizontal.The initial velocity is $v _ { 0 }$ feet per second, and the path of the projectile is modeled by the parametric equations $x = \left( v _ { 0 } \cos \theta \right) t \text { and } y = h + \left( v _ { 0 } \sin \theta \right) t - 16 t ^ { 2 }$ . Select the correct graph of the path of a projectile launched from ground level at the value of $\theta$ and $v _ { 0 }$ .
$\theta = 60 ^ { \circ }$ , $v _ { 0 } = 93$ feet per second

Sensory Adaptation

The process by which sensory receptors become less sensitive to constant or repetitive stimuli over time.

Signal-Detection Theory

A means to quantify the ability to discern between information-bearing patterns and random patterns that distract from the information in the presence of uncertainty.

Just Noticeable Difference

The smallest change in intensity of a stimulus that can be detected by the sensory system.

Absolute Threshold

The minimum stimulus intensity required to be detectable by the senses.
