What is the velocity of an object that has fallen 76 feet

Mathematics

krok68 [10]3 years ago
7 0
Ignoring air resistance...

vf^2-vi^2=2gs, where vf is final velocity, vi=initial velocity, g=acceleration due to gravity, and s is the displacement of the object...

For an object being dropped, vi=0, so we have only have final velocity.

v^2=2gs

v=-√(2gs), g≈-32ft/s^2, s=-76

v=-√(2(-32)(-76))

v=-√4864

v≈ -69.74 ft/s  (to nearest hundredth of a foot per second)

It's negative because the object is falling, or height is decreasing :P

About when does the softball reach its maximum height?
Masja [62]

Based on the given graph, the time when the softball reaches its maximum height is about 1.8 seconds.

<h3>When is the softball at it highest?</h3>

The softball is at its maximum height at the point where the curve begins to go back down.

This means the maximum height is 50 feet.

The time when this softball reaches this height is between 1 and 2 seconds at 0.8.

The time the softball reaches its maximum height is therefore 1.8 seconds.

Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.
Margaret [11]

Answer:

The correct option is 3.

Step-by-step explanation:

Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.

J = 90°, J' = 90°

K = 65°, K' = 65°

L = 25°, L' = 25°

In a rigid transformation the  image and pre-image are congruent. Reflection, translation and rotation are rigid transformation.

In a non rigid transformation the image and pre-image are similar. Dilation is a non rigid transformation.

In a rigid or a nonrigid transformation, the corresponding angles are same. If the corresponding sides are same, then it is a rigid transformation and if the corresponding sides are proportional, then it is a non rigid transformation.

It can be a rigid or a nonrigid transformation depending on whether the corresponding side lengths have the same measures.

Therefore option 3 is correct.
