It would be: Activation Energy = 300 KJ
Hope this helps!
Answer:
33 kg m/s
Explanation:
The momentum of an object is given by:

where
m is the mass of the object
v is the velocity of the object
In this problem, the total mass of the child and the wagon is m =22 kg, while the velocity is v = 1.5 m/s, therefore the momentum is

Because animals are animals and humans hopefully don’t want to be treated like animals, also it is preferred that they don’t eat human food like gum or chocolate…
