HELP PLS ITS BEEN AN 3 HOURS

0.433 s

Explanation:

Let's break the projectile motion into its horizontal and vertical components:

Horizontal component (x):

Vertical component (y):

We want to find the time required for the hurdler to travel a distance of 0.635 m. In order words, his displacement should be 0.635 m in the x-direction.

Since we don't have the final velocity, we can use this constant acceleration equation:

We have three known variables and want to solve for t. Using this equation in the x-direction, we have:

Substitute these values into the equation.

Simplify the equation.

Divide both sides by the horizontal component of the initial velocity.

Since we start with 3 sig figs, we will round this value to 0.433. The time it takes to clear the hurdle is 0.433 seconds.

i think if it were me i whould divide 300 dide 15
