Objects on the moon's surface have an acceleration due to gravity one-sixth that on the earth's. what would the 50.0 kg boy weigh on the moon?

80 N

Explanation:

The acceleration due to gravity on Earth is . On the Moon, it is 1/6 that on the Earth, so the acceleration due to gravity on the Moon is

The weight of the boy on the moon can be calculated as

where m=50 kg is the boy's mass. By substituting in the formula,

force tends to be low and long diustance masses are high

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
