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​

The person can jump 48 m on the Moon

Explanation:

The question parameters are;

The maximum long jump distance of a person on Earth, = 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, , of a projectile motion is found by using the following formula

Where;

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

Therefore, we have;

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, = 1/16 × g

∴ = 1/16 × g = 1/16 × 9.8 m/s² ≈ 0.6125 m/s²

The maximum distance the person can jump on the Moon with the same velocity which was used on Earth is ≈ 48 m

increase masses, decrease separation

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
