Answer:
a)
v=<400, 450+3t, 600-9.81t> m/s
r=<400t, 450t+3/2, 15+600t-9.81/2> m/s
b) attach file
c) t=122.324s
d) z=18369.9854 m
Step-by-step explanation:
a)
The equation for velocity of each component is v=+at, in this case the x-axis component has acceleration 0, the y-axis component has acceleration 3 and the z-axis component has -g, where g=9.81.
The equation for position of each component is x=+t+a/2,
with <, ,>=<0,0,15>.
c) This time is t when z=0, with positive sign.
d)Solving the equation = + 2*a*(z-) for z, with =0.
