Step 1: Convert the mass from grams to kilograms.
The given mass is 15 g.
m=15g×1000g1kg=0.015 kg
Step 2: Identify the given acceleration.
The acceleration is 40.0ms−2.
a=40.0ms−2
Step 3: Use Newton's second law of motion to calculate the force.
The formula for force is F=ma.
F=(0.015kg)×(40.0ms−2)
F=0.6 N
The force acting on the body is 0.6N.
