Afootball player kicks a ball with an initial
velocity of 25 meters per second at an angle of
53° above the horizontal. the vertical component
of the initial velocity of the ball is
a.
25 m/s
b,
d.
20. m/s
10. m/s
c.
15 m/s

20 m/s

Explanation:

The vertical component of the initial velocity of the ball is given by:

where:

is the initial speed

is the angle of launch above the horizontal

In the problem we have

Substituting into the equation,

The vertical component  of the initial velocity of the ball is 20 m/s.

Explanation:

Given data:

Initial velocity is, u = 25 m/s.

Angle of inclination is, .

The vertical component of initial velocity is,

Solving as,

Thus, vertical component  of the initial velocity of the ball is 20 m/s.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
