A 10 m long uniform iron bar pivoted at the center of the bar is subjected to the horizontal forces F; and F2 = 200 N as shown in the picture taken from the the
bar (Bird eye view). Fy acts at X = 4,4 m to the left of the pict not an age
19° with the bar. If the iron bar stays in equilibrium with zero net conquer under these
two forces, what is the magnitude of the force F; to the nearest rester Doar
enter units in the answer
1 - 200 N

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
