Adart leaves a toy dart gun with initial velocity of 7.76 m/s, regardless of the angle it is fired. what is the maximum horizontal distance that the dart can travel? assume that the dart gun is fired at ground level. a. 3.88m b. more information is needed c. 6.14m d. 12.28m

C. 6.14 m

Explanation:

The maximum horizontal distance travelled by a projectile is given by:

where

v is the initial velocity

is the acceleration of gravity

is the angle of launch

From the equation, we see that the maximum range is achieved when the projectile is fired at .

The dart in the problem has an initial velocity of

v = 7.76 m/s

Substituting into the formula, we find the maximum horizontal distance:

technology is the application of the knowledge gained by science.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
