Momentum (in terms of classical mechanics) is defined as p = m*v, where m is the mass and v is the velocity.
Answer:
0.1 m
Explanation:
From the question given above, the following data were obtained:
Mass (m) of ball = 4 Kg
Acceleration due to gravity (g) = 9.8 m/s²
Energy (E) = 4 J
Height (h) =?
The height (h) can be obtained by using the following formula:
E = mgh
4 = 4 × 9.8 × h
4 = 39.2 × h
Divide both side by 39.2
h = 4 / 39.2
h = 0.1 m
Thus, the value of h is 0.1 m

Answer:
<em><u>F1 </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>6</u></em><em><u> </u></em><em><u>N </u></em><em><u>and </u></em><em><u>F2 </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em><em><u> </u></em><em><u>N</u></em>
Explanation:
<em>Formula </em><em>used </em><em>=</em><em>></em><em> </em><em> </em><em>F </em><em>=</em><em> </em><em>m×</em><em>a</em><em> </em><em>and </em><em>v-u=</em><em> </em><em>at</em>
So, as we know force = mass × acc.
so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now
Here u= 0 as the objects are placed at rest initially..
thus, v= at
<em>FOR </em><em>1</em><em>S</em><em>T</em><em> </em><em>BLOCK</em>
16= <math> F1/5 </math> × 5 ==> <em><u>F1 </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>6</u></em><em><u> </u></em><em><u>N</u></em>
<em>FOR </em><em>2</em><em>N</em><em>D</em><em> </em><em>BLOCK</em>
15= <math> F2/ 8 </math> × 5 ==> <em><u>F2=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em><em><u> </u></em><em><u>N</u></em>
