2 Motion and forces

At a launch facility, a powered capsule carrier is tested with different payloads. A force sensor records the horizontal forces during each run.

Run	Mass of carrier and payload in $kg\text{kg}$	Driving force forwards in $N\text{N}$	Resistive force backwards in $N\text{N}$
1	40	150	30
2	60	165	45
3	80	180	60

Explain why these measurements allow the effect of mass on acceleration to be compared fairly.

[2]

In a fourth run, the mass of the carrier and payload is 100 kg. The driving force is 195 N forwards and the resistive force is 75 N backwards.

Calculate the acceleration of the carrier.
