Answer:
The net force on the wagon will be 88.27N 
Step-by-step explanation:
Mass of Wagon = m = 91kg 
Acceleration of wagon = a = 0.97kgm/s^2 
Net force on wagon = F = ? 
According to Newton’s second law of motion: 
“When a force is applied on a body, acceleration is produced in it in the direction of force”. Mathematically, it can be represented as: 
 F = ma ……… (i) 
By putting values in equation (i), 
 F = (91)(0.97) 
 F = 88.27N
