Question

Challenge: a hammer is dropped on planet x. if the hammer has a mass of 3 kg and a weight of 9 n, what is the gravitational acceleration of planet x and is it more or less than that of earth?

Answer 1

To know that we would need to know how long it takes the hammer to drop.

Answer 2

Gravitational acceleration at planet x will be
`g=3m/sec^2`

Acceleration due to gravity on planet x will be less than acceleration due to gravity on earth

Step-by-step explanation:

We have given mass of the hammer m = 3 kg

And weight of the hammer at planet x = 9 N

We know that weight of the body is given by
`W=mg`

`9=3* g`

`g=3m/sec^2`

So gravitational acceleration at planet x will be
`g=3m/sec^2`

As we know that acceleration due to gravity on earth is
`9.8m/sec^2`

So acceleration due to gravity on planet x will be less than acceleration due to gravity on earth
