m/s2

4 (credit).
parachute Two forces act on a parachutist during a drop. One force is the weight W of the parachutist. The other force is the upwards pull P from the parachute harness on the parachutist. The parachutist has a mass of 50 kg.

(a). What is the size of the unbalanced force acting on the parachutist? N

(b). What is the acceleration of the parachutist? m/s2

5 (credit).
trolley A shopping trolley and its contents have a mass of 20 kg. The trolley is pushed with a force P. The friction force acting on the trolley is 20 N. The acceleration of the trolley is 0.5 m/s2.
