How many mL is an espresso?
One shot of espresso is generally about 30–50 ml (1–1.75 oz), and contains about 63 mg of caffeine (3). Important point: The “golden ratio” for espresso is this: a single shot is 30 to 44 mL (1 to 1.5 ounces) of water and 7 grams of coffee

Newton's second law of motion states that the force is equal to the product of the mass and acceleration. It can mathematically be expressed as,
F = m x a
When this equation is transformed to solve for acceleration, this becomes,
a = F / m
The equation suggests that for an object to move, force has to be exerted.
Because each joint is capable of a different measure of its own range of motion
Explanation:
a) F = GmM / r²
F = (6.67×10⁻¹¹) (500) (5.98×10²⁴) / (6.4×10⁶ + 1.5×10⁶)²
F = 3200 N
b) F = ma
3200 = 500a
a = 6.4 m/s²
c) a = v² / r
640 = v² / (6.4×10⁶ + 1.5×10⁶)
v = 7100 m/s
