Answer 1

Answer:

The magnitude of the momentum, = 2, is constant. So, the force is not changing the magnitude of the momentum – it is only changing its direction. The component of the force along the momentum is 0. The component perpendicular to it is non-zero, because the momentum is actually changing

Answer 2

c) Given AB = 6cm

BC = 7cm

angle B = 60°

Let angle A = 90°

By Pythagoras theorem,

Hypotenuse =√ Base^2 + √height^2

BC = √AB^2 + √AC^2

AC = √BC^2 - √ AB^2

AC = √7cm^2 -√ 6cm^2

AC = (√ 49 - √ 36) cm

AC = √13cm

Then, the Area of ∆ ABC = 1/2 × base × height

= 1/2 × 6cm × √13cm

= 12√ 13cm^2
