Arifle is aimed directly at the bulls eye of a target 75 meters away. if the bullet has a speed of 250 m/s, how far below the bulls eye will the bullet hit

Explanation:

Given

Distance of target d=75 m

velocity of bullet v=250 m/s

First taking horizontal motion

as there is no acceleration is horizontal direction therefore

where u=initial velocity

=acceleration

t=time

In this time Vertical distance moved by Bullet is

here

  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
