A gun has a muzzle speed of 80 meters per second. What angle of elevation should be used to hit an object 180 meters away? Negle
olga55 [171]
Knowing the initial velocity and angle, the horizontal range formula is given by   R= V^2sin(2teta) / g, so we can get 
sin(2teta)=Rg/V^2
sin(2teta)= (180 x 9.8)/ 80^2= 0.27, sin(2teta)=0.27, 2teta=arcsin(0.27)=15.66, so teta=15.66/2

teta=7.83°

In designing buildings to be erected in an area prone to earthquakes, what are the things that you need to consider?
il63 [147K]

Answer:

In an earthquake prone area, the things that are needed to be considered for the buildings to stand constant and no cause of damages are as follows-

  • The foundation of the building must be made strong, using large amount of concretes so that it can hold the entire load of the building.
  • The pillars of the buildings are also should be firmed, rigid, strong and thick.
  • The buildings are needed to be construct in such a way that during any seismic event, the forces can be redistributed easily through the body of the building without causing any damage.
  • The buildings must be overall comprised of holding high strength and stiffness.
