Answer: 0.2N
Explanation:
mass of wagon = 100 grams
Convert mass in grams to kilograms
If 1000 grams = 1kg
100 grams = (100/1000) = 0.1kg
Acceleration of wagon = 2m/s/s
Force on the wagon = ?
Recall that Force is the product of mass of an object by the acceleration by which it moves.
i.e Force = mass x acceleration
Force = 0.1kg x 2m/s/s
Force = 0.2N
Thus, the force on the wagon is 0.2Newton
