A is not correct because x is not the distance moved in the direction of the
Time Time force
C is not correct because y is not the distance moved in the direction of the

(Total for Question 6 = 1 mark)
5 The only correct answer is D ��(202 + 352 )� 1
A is not correct because the forces are not in the same direction
B is not correct because the forces should each be squared before square
rooting the sum of the squares
C is not correct because the sum has not been square rooted
6 The only correct answer is B 1
A is not correct because this shows constant velocity not constant
