Question

A body has weight 20N. How much force is required to move it vertically upward with an acceleration of 2m/s^2?

Answer 1

@MelissaHolmes

Answer 2

The force should overcome the given weight and produce an acceleration of 2m/s^2

Answer 3

F2-F1 = m*a

Answer 4

F2 = F1 + m*a
F2 = 20 + m *2

Answer 5

Now we know only the weight NOT Mass - and given weight you can calculate mass if you know the value of 'g' of the place

Answer 6

g =9.8 m/s^2 for earth
and Weight = m*g
