Good Day

Problem:

a ball thrown straigjt upward. If it takes 4.25 seconds to reach the top of its path, what is its initial speed?

Given Data:

Vi (initial velocity) = ? unknown

Vf (final velocity) = 0 m/s (at top)

t (time)  =  4.25 s

a (acceleration) = -9.8 m/s² (going up decelerating)

Solution:

We can solve the problem using the formula a = (Vf-Vi)/t

To solve for Vi, we can use - Vi = at Vf

- Vi = at Vf

- Vi = -9.8 m/s² × 4.25 s + 0 m/s

- Vi = - 41.65 m/s + 0 m/s

( - Vi = - 41.65 m/s) × -1

  Vi = 41.65 m/s

Hope it helps....=)

Initial Velocity is 41.65 m/s

Why Clouds Are White And Dark?

Why clouds are white and dark?   Colour of the clouds depends on size and number of particles with which cloud is made of: 1) If cloud contains only a small amount of droplets and ice crystals, sunlight penetrates it easily and scattered. We percieve it as white. 2) If cloud(like rain cloud) contains high amount of heavy water droplets with larger size due to condensation, little light penetrates it. Further, all the light enters is scattered out and we percieve it as dark.

Bakit Kailangan Sumunod Ang Negosyong Panserbisyo At Produkto Sa Lokal Na Pamahalaan

Bakit kailangan sumunod ang negosyong panserbisyo at produkto sa lokal na pamahalaan   Ang lokal na pamahalaan ang representative ng national government. Binigyan siya ng awtoridad upang kontrolin ang mga proseso, negosasyon sa kaniyang teritoryo. Pananagutan naman na gampanan ito ng lokal na pamahalaan dahil ang kaniyang kita at performance sa national level ay nakadepende sa kaniyang pamamalakd at ilang evaluations sa products and services. Kaya naman ang mga organsisasyon o negosyo ay diniderektang makipag-ugnayan at makipagtulungan sa lokal na pamahalaan upang mabigyan ng opurtunidad na gumalaw ng legal.
