14. An 800 kg engine pulls off a train of 10 wagons
each of 1,000 kg along a horizontal track. If the
engine exerts a force of 40,000 N and the track
offers a frictional force of 5,000 N, calculate the
acceleration produced.

Explanation:
total mass = 10(1000) + 800=10800kg
total force=40000-5000=35000N
F=ma
a=F/m
a=35000/10800=3.24 m/s²
