Answer:
D. vo = 125(2)^1/2
Step-by-step explanation:
Range of a projectile is the defined as the distance covered in the horizontal direction.
Range = U²sin2θ/g
U is the speed of the object
θ is the angle of launch
g is the acceleration due to gravity
If the target is 1000 ft away horizontally, range = 1000ft
θ = 45°
g = 32ft/s²
1000 = U²sin2(45°)/32
32000 =U²sin90°
32000 = U²
U = √32000
U = 125√2 m/s

I cannot understand the question of first part so second part
Y - 3 + 5z
Putting values of y and z
6 - 3 + 5(3)
3 + 15
18
