- For the woman being pulled forward on the toboggan in Figure 4.33, is the magnitude of the normal force exerted by the ground on the toboggan (a) equal to the total weight of the woman plus the toboggan, (b) greater than the total weight, (c) less than the total weight, or (d) possibly greater than or less than the total weight, depending on the size of the weight relative to the tension in the rope?On her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.20-kg basket of goodies beside her. A wolf came along, spotted the basket, and began to pull on the handle with a force of 6.40 N at an angle of 25° with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 13.5 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling from the vertical? The whole question did not paste in on my last attempt.Three forces acting on an object are given by F1 = (-2.00 i + 2.00 j) N, and F2 = (5.00 i – 3.00j) N, and F3 = (- 45.0 i) N. The object experiences an acceleration of magnitude 3.75 m/s2. (a)What is the direction of the acceleration? (b) What is the mass of the object? (c) If the object isinitially at rest, what is its speed after 10.0 s? (d) What are the velocitycomponents of the object after 10.0 s?

I was given the WRONG answer this morning! The force that Red applied was 13.5N NOT 12.2 N! Use 13.5 N! I use this service primarily to check my work. If the "experts" are using the wrong values, I question if they will use the right mathematical procedures if I really have a challenge!as a fish jump vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the downward force due to gravity. a force chinook salmon has a length of 1.50 m and a mass of 48.5 kg. if the fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 5.80 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine the following. a. the salmon's acceleration b. the magnitude of the force F during this intervalAsap
