Answer:
F = 30 N
Step-by-step explanation:
Given that,
Mass of a toy train, m = 1.5 kg
The acceleration of the toy-train, a = 20 m/s²
We need to find the force acting on it. We know that, net force acting on an object is given by :
F = ma
Substitute all the values,
F = 1.5 × 20
F = 30 N
Hence, the net force acting on the toy train is equal to 30 N.
