Physics: Suppose that on earth you can throw a ball vertically upward a distance of 1.20 m. given that the acceleration of gravity on the moon is 1.67 m/s2, how high could you throw a ball on the moon? (take the y-axis in the vertical direction, and assume that the location of your hand is at y = 0.)

7.04 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity = 0

s = Displacement on Earth = 1.2 m

a = Acceleration due to gravity on Moon = 1.67 m/s²

a = Acceleration due to gravity Earth= 9.81 m/s²

Accelration going up is considered as negetive

Initial Velocity of the ball

$v^2-u^2=2as\\\Rightarrow -u^2=2as-v^2\\\Rightarrow -u^2=2\times -9.81\times 1.2-0^2\\\Rightarrow u=\sqrt{2\times 9.81\times 1.2}\\\Rightarrow u=4.85\ m/s$

Assuming that the ball is thrown with the same velocity on the Moon, displacement of the ball is

$v^2-u^2=2as\\\Rightarrow s=\frac{v^2-u^2}{2a}\\\Rightarrow s=\frac{0^2-4.85^2}{2\times -1.67}\\\Rightarrow s=7.04\ m$

The displacement of the ball on the moon is 7.04 m

Explanation:

The eight nations' spheres in Qing China were designated primarily for trade purposes. Great Britain, France, the Austro-Hungarian Empire, Germany, Italy, Russia, the United States, and Japan each had exclusive special trading rights, including low tariffs and free trade, within Chinese territory
