can i get help with these questions please

HW4, Chapter 4&5 5. E SSM A person in a kayak starts paddling, and it accelerates from 0 to 0.60 m/s in a distance of 0.41 m. If the combined mass of the person and the kayak is 73 kg, what is the magnitude of the net force acting on the kayak? 19. H SSM A 325-kg boat is sailing 15.0" north of east at a speed of 2.00 m/s. Thirty seconds later, it is sailing 35.0% north of east at a speed of 4.00 m/s. During this time, three forces act on the boat: a 31.0-N force directed 15.0" north of east (due to an auxiliary engine), a 23.0-N force directed 15.0 south of west (resistance due to the water), and Fw (due to the wind). Find the magnitude and direction of the force Fw- Express the direction as an angle with respect to due east. (Hint: Use the component method: (i) find the acceleration components first from change in velocity vector; (ii) find the components of the forces.) 27. E SSM Synchronous communications satellites are placed in a circular orbit that is 3.59 x 10' m above the surface of the earth. What is the mag- nitude of the acceleration due to gravity at this distance? 49. M SSM A person is trying to judge whether a picture (mass = 1.10 kg) is properly positioned by temporarily pressing it against a wall. The pressing force is perpendicular to the wall. The coefficient of static friction between the picture and the wall is 0.660. What is the minimum amount of pressing force that must be used? (Hint: use the maximum static friction equation.)
