0 -1252-2??
0 -1252 +2e?
0 -1252 +8st – 202
0 -12s2+11st – 2x2
Answer:
-616
Step-by-step explanation:
None of these answers are correct... maybe you entered the equation in wrong. There are no variables so answers B,C, and D would be incorrect. And A is incorrect as well. Again, check the equation... may be wrong.
2.2^9
2^10 • 2²
2^-2 2^11
(2.2.2.2.2).(2.2.2.2)
Answer:
Step-by-step explanation:
The law of exponents says that when the base is same in multiplication, add the exponents.
The answer is 2 to the power of 9.
The kick is good! The ball clears the crossbar by approximately 14 feet.
The kick is good! The ball clears the crossbar by about 4 feet.
The kick is not successful. The ball is 2 feet too low.
Question:
1) The kick is good! The ball passes about 10 feet above the crossbar.
2) The kick is good! The ball clears the crossbar by approximately 14 feet.
3) The kick is good! The ball clears the crossbar by about 4 feet.
4) The kick is not successful. The ball is 2 feet too low.
Answer:
The correct option is;
3) The kick is good! The ball clears the crossbar by about 4 feet.
Step-by-step explanation:
Here we have
Horizontal distance from goal, x = 36 yards = 108 ft
Vertical distance of goal, y = 10 ft
Angle of elevation of ball = 34°
Initial velocity of ball, v₀ = 68 ft/s
∴ Vertical component of velocity = = v₀×sin(θ₀)×t - g×t
Horizontal component of velocity = vₓ = 68×cos(34) = 56.375 ft/s
The equation for projectile motion is as follows
x = x₀ + v₀×cos(θ₀)×t
y = y₀ + v₀×sin(θ₀)×t - 1/2×g×t²
Where:
x₀ = Initial horizontal displacement of the ball = 0
y₀ = Initial vertical displacement of the ball = 0
t = Time of flight of the ball
Therefore;
108 = 0 + 68×cos(34)×t which gives;
t = 108/56.375 = 1.916 seconds
Hence, y = y₀ + v₀×sin(θ₀)×t - 1/2×g×t² gives;
y = 0 + 68×sin(34)×1.916 - 1/2×32.2×1.916²
y = 72.85 - 59.09 = 13.76 ft, hence the vertical location of the ball at 36 yard is 13.76 ft where the crossbar is at 10 ft hence the ball clears the crossbar by 13.76 ft - 10 ft = 3.76 ft ≈ 4 ft
Therefore, the kick is good! The ball clears the crossbar by about 4 feet.
