Answer:
The speed of the soccer ball at height point is less than its initial speed
Explanation:
The initial velocity of the soccer can be written in vector form as
= v cos θ î + v sin θ j
where is initial velocity of the ball
v is the initial speed of the ball
Assume soccer ball is kicked at an angle θ with an horizontal and initial speed vm/s. Its horizontal component will be as,
= v cos θ
= v sin θ
At the maximum height, the vertical component becomes zero. therefore, the velocity of the soccer at the maximum point can be written as,
= v cos θ j
where, is velocity of the soccer ball at maximum height
The amount of C-14 at time t is
where
N₀ = inital amount of C-14
t = years
K = 0.0001 = 10⁻⁴
When the skull was discovered, the amount of C-14 contained 43% of N₀.
Therefore
Answer:
The age of the skull s 8440 years (nearest integer)
where
N₀ = inital amount of C-14
t = years
K = 0.0001 = 10⁻⁴
When the skull was discovered, the amount of C-14 contained 43% of N₀.
Therefore
Answer:
The age of the skull s 8440 years (nearest integer)
