DUE IN 3 HOURS! PLEASE HELP AND SOLVE A-E. For a projectile with initial velocity of 51.5 m/s and angle of elevation equal to 4 degrees.
a) Compute the horizontal velocity of the projectile in m/s.
b) Compute the vertical velocity in m/s.
c) Compute the time of flight for the projectile.
d) Compute the distance downrange.
e) Compute the maximum height reached by the projectile.

Below

Explanation:

c) To find the time of flight of a projectile (assuming from the given information that there is no vertical displacement) you can use this formula :

     t = 2(Vi) Sinx / g

     t = 2(51.5m/s) Sin(4) / 9.8 m/s^2

     t = 0.733 seconds

    t = 0.73 seconds

d) To find the displacement in the x-direction you can use this formula :

     dx = vi^2 sin(2x) / g

     dx = (51.5m/s)^2 sin(2(4)) / 9.8m/s^2

     dx = 37.6654 m  

     dx = 37.7 meters

e) To find the peak height of the projectile you can use this formula :

     v^2sin^2(x) = 2gh

     (51.5m/s)^2sin^2(4) = 2(9.8m/s^2)h

     h = 0.658 meters

     h = 0.66 meters

Hope this helps! Best of luck <3

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
