check answer please. An object is pulled with 3 forces: 1 at 20n to the right another at 40n to the right and the third at 30n to the left. The net force is 30n to right

Can someone tell me how to figure this out. Fido weighs 120N & carries Trixie who weighs 40N on her back. The support force on fidos feet is. 160n - 40n - 120n -more than 160n

Science
When you stand at rest on a floor the number of vertical force acting on you is A 0 B 1 C 2 D 3 E 4

Science
A 50N object falling in air experiences 30N of air resistance. The amount of net force on the falling object is A 0n B 20n C 50n D 80n

Science
thank you I couldn't remember the formula

Science
At the end of 2 seconds of free fall an object released from rest will have a speed of A. 5m/s B 10m/s C 15m/s D none of the above
