Question

A 147N iron ball weighs 15kg. What is the acceleration of the ball due to gravity?

Answer 1

Weight of an object is defined as attraction force due to gravity

so here we will have

`W = mg`

now we know that

`W = 147 N`

mass = 15 kg

now acceleration due to gravity is given as

`147 = 15* g`

`g = (147)/(15)`

`g = 9.8 m/s^2`

so here acceleration due to gravity is 9.8 m/s^2
