1 answer:

8 0

Chemical properties are observed when matter or substance changes to form a new kind of matter or substance.

<h3>What is Chemical properties?</h3>

This is the term used to describe the ability of a substance or matter to react and form new substance. Chemical properties are used during chemical reaction to be able to control the reaction and get a certain product

we can conclude that chemical properties are observes during chemical reaction to ascertain the new substance or matter to be formed

A squirrel on a limb near the top of a tree loses its grip on a nut, so that the nut slips away horizontally at a speed of 1.5m/

tatiyna

Answer:

The height of the squirrel $h =113 \ m$

Explanation:

From the question we are told that

The horizontally speed is $v = 1.5 m/s$

The horizontal distance $d = 7.2 \ m$

Generally the the time taken is mathematically represented

$t = \frac{d}{v}$

=> $t = \frac{7.2}{1.5}$

=> $t = 4.8 \ s$

Generally from kinematic equation we have that

$h = ut + \frac{1}{2} gt^2$

Here u is the initial velocity of nut in the vertical and the value is 0 m/s

$h = 0 * 4.8 + \frac{1}{2} * 9.8 * (4.8)^2$

=> $h =113 \ m$
