Jake uses a fire extinguisher to put out a small fire. When he squeezes the handle, the flame retardant is released from the extinguisher with considerable force. As a result, Jake has to reinforce his grip on the extinguisher to hold it in place as it pushes back into his hands. The projectile in this scenario is the . The recoil in this scenario is the . The force on the flame retardant is the force on the extinguisher. The mass of the flame retardant is the mass of the extinguisher. The acceleration of the flame retardant is the acceleration of the extinguisher.

Two children are pulling and pushing a 30.0 kg sled. The child pulling the sled is exerting a force of 12.0 N at a 45o angle. The child pushing the sled is exerting a horizontal a force of 8.00 N. There is a force of friction of 5.00 N. What is the weight of the sled? N What is the normal force exerted on the sled? Round the answer to the nearest whole number. N What is the acceleration of the sled? Round the answer to the nearest hundredth. m/s2
