Question

A block weighs 50 N due to the acceleration of gravity 9.8 m/s^2. What is the mass of the block?

Answer 1

Answer:

m = F/a

= W/g

= 50N/9.8 m/s^2

= 5.1 kg (2s.f.)

Answer 2

Answer:

Explanation:

Given,

Force, F = 50 N

Acceleration of gravity, g = 9.8 m/s²

To Find,

Mass of the block, m

Formula to be used,

Newton's 2nd law,

F = ma

m = F/a

Solution,

Putting all the values, we get

m = F/a

⇒ m = 50/9.8

⇒ m = 5.1 kg

Hence, the mass of the block is 5.1 kg.
