When a system is displaced, it encounters a net force in the same direction as the displacement.

(2a)

When a system is displaced from equilibrium, it feels a net force in the same direction as the displacement. If it is displaced even little from its equilibrium position, it tends to accelerate away from it, whereas in neutral equilibrium, the system is unaffected by displacement from its original location.

(2b)

(ii)Low centre of gravity

(ii)Large contact surface area

(3a)

Velocity is a vector quantity with the SI unit of ms-1. It is defined as the rate of change in a body’s displacement.

x-25/100-25 = 67-0/100-0

x-25/75 = 67/100

4 = 61*3 (x-25)

4x-100 = 201

4x = 201+100+100+100+100+100+100+100+100

16cm u u u u u u u u

v/u = m = 4

:. v =4u :. v =4u :. v =4

v = 416 = 64cm v = 416 = 64cm v = 416 = 64cm

Remember that 1/f = 1/u + 1/v

1/16 + 1/64 = 1/f

4+1/64 = 1/f

5/64 = 1/f

f = 64/5 = 12.8cm f = 64/5 = 12.8cm f = 64/5 = 1
