Answer:
84 grams and 5 ounces
Step-by-step explanation:
because one ounce equals 28 grams, that means 3 ounces = 3 * 28 = 84
because 28 grams equals 1 ounce, 140 grams = 140 / 28 = 5 ounces
Answer:
b = 2
Step-by-step explanation by completing the square:
Solve for b over the real numbers:
b^2 - 4 b + 4 = 0
Write the left hand side as a square:
(b - 2)^2 = 0
Take the square root of both sides:
b - 2 = 0
Add 2 to both sides:
Answer: b = 2

Answer: A projectile reaches its highest point when its vertical velocity component is zero.
Step-by-step explanation:
In projectile motion, objects moves in parabolic path.
Projectile motion is a type of motion in which an object moves in a bilaterally symmetrical, parabolic path. Projection motion happens when the force is applied at the start of the trajectory (where the object follows) which follows an interference which is gravity. Gravity takes over and afterwards the object accelerates downwards. The acceleration is constant so the vertical velocity (Vy) varies linearly. The maximum height of the projectile which is the highest height is reached when the vertical velocity (Vy) is equal to zero.
After the projectile reaches its maximum height which is its highest point, it begins to drop downwards.
