Answer 1

Acceleration is the rate of change of velocity with time.

Answer 2

Answer:

(xiii) 22m – (12.1/2)n – 15p + 16n

= 22m – (25/2)n – 15p + 16n

= 22m + 16n – (25/2)n – 15p

= 22m + ((32n – 25n)/2) – 15p

= 22m + (7n/2) – 15p

= 22m + (3.1/2)n – 15p

(xiv) 6p + (2/3)q – (1.1/2)p + (1/3)q + 2q

= 6p – (3/2)p + (2/3)q + (1/3)q + 2q

= ((12p – 3p)/2) + ((2q + q + 6q)/3)

= (9/2)p + 3q = (4.1/2)p + 3q

(xv) (2. 2/3)xy – (3.1/2)xy + (3.1/3)xy – (2.1/2)xy
