This is 7th grade honors math/science.

Answer 1

Hello Ava. In order to answer this question, you must know Newton's second law of motion. Newton's second law of motion states that F=MxA, where F is net force (in Newtons) , M is mass (in kg) and A (in m/s^2) is acceleration. The values for mass and acceleration are provided in the problem. You just have to substitute those values into the equation and solve for F.

F=MxA

F= (40 kg)(2.5 m/s^2)

F = 100 N
