Children slide down a frictionless water slide that ends at a height of 1.80 m above the pool. If a child starts from rest at po

Lerok [7]

Answer:

$h = 1.75 m$

Explanation:

As we know that height of the slide is given as

$h = 1.80 m$

so time taken by the child to hit the water from the slide is given as

$t = \sqrt{\frac{2h}{g}}$

now we will plug all data in it

$t = \sqrt{\frac{2(1.80)}{9.81}}$

$t = 0.605 s$

now we know that the horizontal distance moved by it is given as

$L = v_x t$

$3.55 = 0.605 v_x$

$v_x = 5.86 m/s$

now by energy conservation

$mgh = \frac{1}{2}mv^2$

so height of point A is given as

$h = \frac{v_x^2}{2g}$

$h = \frac{5.86^2}{2(9.81)}$

$h = 1.75 m$

Mike walked 450 m west. He then turned and walked 150 m to the east in 300 seconds. what was his velocity?

enyata [817]

Velocity = Displacement / time

Displacement = 450 - 150 = 300.

By the time he walked 150 East, he walked backwards. Hence displacement is 300 m West.

Velocity = 300m / 300 s

= 1 m/s

All of the following use subjective scoring EXCEPT Archery.

<h3>What is subjective scoring?</h3>

Subjective scoring is an important and powerful tool you can use to add assessment items that are not easily scored.

Archery is scored based on point values that is assigned to the rings made on the target. Others are not point scoring sports.

Thus, all of the following use subjective scoring EXCEPT Archery.
