Correct? Please let me know if my logic is off. Thank you =] Given Problem At the bow of a ship on a stormy sea, a crewman conducts an experiment by standing on a bathroom scale. In calm waters, the scale reads 180 lb. During the storm, the crewman finds a maximum reading of 234 lb and a...

Correct? Please let me know if my logic is off? =D Given Problem You pull upward on a stuffed suitcase with a force of 103 N, and it accelerates upward at 0.731 m/s2. (a)What is the mass of the suitcase? (b)What is the weight of the suitcase? Relevant equations F = ma W = mg...

Correct? Please let me know if my logic is off. Given Problem A shopper pushes a 6.1 kg shopping cart up a 13° incline, as shown in the figure. Find the magnitude of the horizontal force, F, needed to give the cart an acceleration of 1.51 m/s2. Relevant equations F = ma Fy = F1cos13°...

Thank you =] Made the correction but apparently my answer has the wrong sign? Answer should be in x direction which I thought was what I was finding. Slightly confused =/

Thank you very much! Made correction to Part B and treated m2 and m3 as a single block: F = (m2 + m3) * (a) F = (3.20kg + 4.30kg) * (.852273m/s2) F = (7.5kg) * (.852273m/s2) F = 6.39205 N

Correct? Please let me know if my logic is off. =] Given Problem As shown in the figure, a force of magnitude 7.50N pushes three boxes with masses m1 = 1.30 kg m2 = 3.20 kg m3 = 4.30 kg (a) Find the magnitude of the contact force between boxes 1 and 2. (?N) (b) Find the magnitude...

Correct? 1. Given Problem A drag racer crosses the finish line doing 203mi/h and promptly deploys her drag chute (the small parachute used for braking). (a)What force must the drag chute exert on the 878kg car to slow it to 45.2 mi/h in a distance of 199m? (b)Describe strategy. 2...
