My Notes Ask Your Teacher car travels horizontally for 192 ft, then climbs 147 ft at an angle of 32.00 above the horizontal. It then moves 147 ft at an angle of 43.0° below the horizontal. If we take the initial horizontal motion of the car to be along t he tx-axis, what is the cars displacement? (Give the magnitude of your ounterclockwise from the +x-axis.) answer, in ft, to at least four significant figures and give the direction of your answer in degrees c magnitude direction ft o counterclockwise from the +x-axis Need Help?

Answer #1

1.

net horizontal force

Fx = F1 cos x = 5.4 cos 26 = 4.853 N

net vertical force

Fy = F1 sin x + F2 = 5.4 sin 26 + 5 = 7.367 N

Magnitude of net force

F^2 = Fx^2 + Fy^2

F = 8.822 N

dieection,

phi = arctan ( 7.367 / 4.853) = 56.625 ccw from +x axis
