Two rugby players go into a tackle Two rugby players go into a tackle. Player A has a mass of 71 kg and is accelerating at a rate of 2m/s/s. Player B has a mass of 83 kg and is accelerating at a rate of 3m/s/s. Using Newton’s Second Law of Motion, calculate the resultant force at the point of impact. You must show your working. (3)

Two rugby players go into a tackle Two rugby players go into a tackle. Player A has a mass of 92 kg and is accelerating at a rate of 2m/s/s. Player B has a mass of 65 kg and is accelerating at a rate of 3m/s/s. Use Newton’s 2nd Law of Motion to: (a) calculate the resultant force at the point of impact. You must show your working. (4) (b) identify which player the resultant force favours (1) a) Newton’s 2nd Law of Motion - force = mass x acceleration (F = MA) (1) Player A: F = 92 x 2 = 184 N (1) Player B: F = 65 x 3 = 195 N (1) Resultant force of 11 N (1) b) Player B
