Answer:
20 m/s
Explanation:
initial velocity, u= 25m/s
u has two components. one in horizontal and in one vertical.
so,
u sin theta = vertical component.
=> u sin theta = 25× 4/5
= 20 m/s
Answer:
<em>The Sun produces energy by the process of nuclear fusion. Nuclear fusion occurs when lighter nuclei combine to produce a larger, heavier nucleus. In the process, energy is released. Nuclear fusion requires very high temperatures and pressures. Nuclear fusion occurs in the core of the Sun when hydrogen atoms combine to form helium atoms.</em>

A quantity which have both magnitude and direction is know as vector quantity.
Resultant vector is 6.81 m south east.
Triangle law of vector addition is when two vectors are represented as two sides of the triangle with the order of magnitude and direction, then the third side of the triangle represents the magnitude and direction of the resultant vector.
Since, vector K is 3.0 m north and vector L is 8.6 m southeast
So, angle between vectors K and L is,
90+45 = 135 degree
Resultant vector, 

So, Resultant vector R is 6.81 m with direction of southeast.
