An object of mass m has these three forces acting on it (there is no normal force, "no surface"). f1 = 1 n, f2 = 9 n, and f3 = 5 n. when answering the questions below, assume the x-direction is to the right, and the y-direction is straight upwards.

solved

Explanation:

a) F_net = (F2 - F3)i - F1 j

b) |Fnet| = sqrt( (F2 - F3)^2 + F1^2)

= sqrt( (9- 5)^2 + 1^2)

= 4.123 N

c) θ = tan^-1( (Fnet_y/Fnet_x)

= tan^-1( -1/(9-5) )

= -14.036°

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

im sorry i dont know
