Question

On a planet far, far ay, an astronut picks up a rock The rock has a mass of 5.00 kg and on this particular planet its weight is 400N. If the astronaut erts an upward force of 462 Non the rock, what is its celeration

Answer 1

`12.4 ms^(-2)`

Step-by-step explanation:

on the specific planet ,

weight =400 N acts downwards

astronaut gives an upward force of 462 N

according to the Newton's second law of motion ,

applying Force= mass * acceleration upwards

462 - 400 =5 * a

acceleration =
`12.4 ms^(-2)`
