X=9m
T=0.006
V= 1/T
V= 9m/0.006 V=1500 m/s
Or simply 9/0.006=1500
Y₀ = initial position of the balloon at the top of the building = 44 m
Y = final position of the balloon at halfway down the building = 44/2 = 22 m
a = acceleration of the balloon = - 9.8 m/s²
v₀ = initial velocity of the balloon = 0 m/s
v = final velocity of the balloon = ?
using the kinematics equation
v² = v₀² + 2 a (Y - Y₀)
inserting the values
v² = 0² + 2 (- 9.8) (22 - 44)
v = 20.78 m/s
Answer:
to get it u have to multiple 6=00 time 89 to get the number 21 than plus it by 22 what is 31
