Answer:
F = 37.72 Newtons
Step-by-step explanation:
To solve this problem, we can use Newtons second law that states: F = (mass) x (acceleration).
he mass of the wagon is 15 kg, and the mass of the handle is 1.4 kg. The total mass of the load (wagon + handle) is 15 kg + 1.4 kg = 16.4 kg.
The acceleration of the wagon and handle is given as 2.3 m/s². Using Newton's second law, we can write:
F = (mass) x (acceleration)
F = 16.4 kg x 2.3 m/s²
F = 37.72 N
The child exerts a force of 37.72 Newtons on the wagon and handle.
Hope this helps!
