Projectile Motion A projectile, launched over level ground from a
height of 450 meters above the flat sur face below, has an initial
speed of 175 m/s . The projectile is launched at a 43.5 degree
angle in relation to the horizontal direction
a What are the initial horizontal and vertical components of
the velocity of the projec tile?
bIn terms of the initial horizontal and vertical components of
the velocity, write down equations for the motion of the x and y
coordinates of the projectile. By this we mean what is the x
coordinate as a function of time, and what is the y coordinate as a
function of time?
cIn terms of the initial horizontal and vertical components of
the velocity, calculate the horizontal range of the
projectileRemember to take into consideration that the projectile
is launched from a height above the surface
d. What is the maximum height attained by the projectile above
the flat surface?
e. What is the magnitude and the direction of the acceleration
at the moment the pro jectile reaches its maximum
height?
