Answer:
x<−0.00325153
x> 0.00325153
Step-by-step explanation:
-1/2 (3^(2)+7) x >32
-1/2 (3^(9) x >32
-1/2 (19683) x >32
-9841.5 x >32
x<−0.00325153
x> 0.00325153
Answer:
t = 9.08 sec
Explanation :
This requires the use of the kinematic equations.
u = initial velocity = 21.8 m/s
v = final velocity = 0
t = time = what we're trying to find.
So we use the equation that relates d, u, v and t. This is
d = distance = 99m
d = 
and since v = 0 this reduces to d = 
which rearranges to t =
t =
=9.08 seconds
t = 9.08 sec
