so then its just 30kg*-2.5m/s^2?

so 30kg*(-9.8m/s^2+-2.5m/s^2)

the net force on the boy

Yes 30kg

I thought it was -2.5m/s^2

I think I have the force of Earth on boy at 144 N and the force of the elevator at -2500N, is that right?

For #2 is the two forces on the boy Force of elevator on boy and Force of Earth on Boy(gravity)?

Homework Statement A 30kg boy is in a 1000kg elevator moving at +5m/s when it comes to a stop in 2 seconds. During the slow down... 1.what is the acceleration of the boy and the elevator? 2. what is the net force acting on the boy? 3.What is the force of the elevator on the boy? Homework...

Thank you so much it helps a lot to be able to talk a problem out

oh 2m/s^2?

so the acceleration would be 2 m/s?

acceleration= all forces working on object/mass?

Homework Statement A 2000 kg boat's motor can exert a force of 6000N. The water provides a resistive force of 2000N. What is the magnitude of the acceleration. Homework EquationsThe Attempt at a Solution that the boat has a 4000 N total force going foward
