Two children fight over a 200 g stuffed bear. the 25 kg boy pulls to the right with a 15 n force and the 20 kg girl pulls to the left with a 17 n force. ignore all other forces on the bear (such as its weight). at this instant, can you say what the acceleration of the bear is?

Jovani Morrison · Answer 1

M = 200 g = 0.2 kg, the mass of the stuffed bear

F₁ = 15 N, the force acting to the right on the bear

F₂ = 17 N, the force acting to the left on the bear

The net force acting on the bear is 17 - 15 = 2 N, acting to the left

The acceleration, a, of the bear is given by

a = (2 N) / (0.2 kg) = 10 m/s²

Answer: 10 m/s², to the left.
