Question

hey....!!

♥️Soln plzzz!!

A weightlifter can lift 90 kg mass on the surface of the earth. How much mass can he lift on the moon? The acceleration due to gravity on the earth is 9.8m/s^2 and that on the moon is 1.67m/s^2. ​

Answer 1

HE CAN LIFT A MASS OF 15 KG ON EARTH.

BUT ON THE MOON HE CAN LIFT 6 X 15 = 90 KG.

BECAUSE THE ACCELERATION DUE TO GRAVITY ON THE MOON IS ABOUT ONE SIXTH OF EARTH.

IF WE APPLY IN THE SAME FORCE THAT MEANS A CONSTANT FORCE IS APPLIED.

LET'S TAKE ACCELERATION DUE TO GRAVITY ON THE SURFACE OF EARTH AS 10 M/S²

THEN THE ACCELERATION DUE TO GRAVITY ON THE MOON BECOMES 10 / 6 M/S²

THAT IS 5 / 3 M/S²

IF A PERSON CAN LIFT 15 KG OF MASS ON EARTH THAT MEANS IS APPLYING THE FORCE OF 15 X 10 = 150 NEWTONS.

AS THE FORCE IS CONSTANT,

150 = M × 5/3

M = 150 / (5/3)

M = 90 KG

AS WE CAN SEE, 15 KG OF MASS ON EARTH BECOMES 90 KG OF MASS ON MOON THAT IS EXACTLY THE SIX TIME OF MASS ON EARTH.

SO,

WE CAN SAY THAT AN OBJECT OF W WEIGHT ON THE EARTH BECOMES 6W ON THE MOON..

PLZ MARK IT AS BRAINLIEST ANSWER

Answer 2

Hey!!

A weightlifter can lift 90 kg mass on the surface of the earth. How much mass can he lift on the moon? The acceleration due to gravity on the earth is 9.8m/s^2 and that on the moon is 1.67m/s^2.

Mass on Earth = 90kg,

g on Earth = 9.8 ms—²

Force exerted by a weightlifter = mg

= 90×9.8

= 882N

As force is constant.

882N = mass on Moon × g on Moon

=) 882 = m × 1.67

=) 528.14kg.
