if a person can jump maximum along distance of 3m ,on the earth how far could be jump on the moon where acceleration due to gravity is 1÷16 of that on the earth​

Sagot :

Answer:

The person can jump 48 m on the Moon

Explanation:

The question parameters are;

The maximum long jump distance of a person on Earth, [tex]R_{max}[/tex] = 3 m

The acceleration due to gravity on the Moon = 1 ÷ 16 of that on Earth

The distance the person can jump on the Moon is given as follows;

A person performing a jump across an horizontal distance on Earth (under gravitational force) follows the path of the motion of a projectile

The horizontal range, [tex]R_{max}[/tex], of a projectile motion is found by using the following formula

[tex]R_{max} = \dfrac{u^2}{g}[/tex]

Where;

g = The acceleration due to gravity = 9.8 m/s²

Therefore, we have;

[tex]R_{max} = 3 \, m = \dfrac{u^2}{9.8 \, m/s^2 }[/tex]

u² = 3 m × 9.8 m/s² = 29.4 m²/s²

Therefore, on the Moon, we have;

The acceleration due to gravity on the Moon, [tex]g_{Moon}[/tex] = 1/16 × g

∴ [tex]g_{Moon}[/tex] = 1/16 × g = 1/16 × 9.8 m/s² ≈ 0.6125 m/s²

[tex]R_{max \ Moon} = \dfrac{u^2}{g_{Moon}} = \dfrac{29.4 \ m^2/s^2}{0.6125 \, m/s^2 } \approx 48 \, m[/tex]

The maximum distance the person can jump on the Moon with the same velocity which was used on Earth is [tex]R_{max \ Moon}[/tex] ≈ 48 m
