A soccer ball is kicked at an angle of 40 degrees with an initial velocity of 14 m/s. What is the horizontal velocity in m/s? (Do not state units, and give
answers to the hundredths place.) *

Explanation:

Projectile Motion

It's the type of motion that experiences an object launched near the Earth's surface and moves along a curved path exclusively under the action of gravity.

Being vo the initial speed of the object, and θ the initial launch angle, the two components of the velocity are given by:

The soccer ball is kicked at an angle of 40° with an initial speed of vo=14 m/s.

The horizontal component is:

Calculating:

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

conservation of mass

mass before something happens = mass afterwards
