Question

Using jet backpacks, three astronauts pusn a 110 kg asteroid toward a processing dock. The first astronaut applies F1 = 32 N at theta 1 = 30 degree . the second astronaut applies F2 = 55N at theta 2 = 0 degree , and the last astronaut applies F3 = 41 N at theta 3 = 60 degree as shown. Let the mass of the block Be 8.6 kg and the angle theta = 35 degree for the friction less surface. A firefighter with a weight of 778 N slices down a vertical pole with an acceleration of 2.84 m/s2, directed downward. 35.0 degree )By a constant force F at a constant speed. The fgure shows an overhead view of a 0.225 kg blouse and two of the three horizontal forces applied to it by mad Black Friday sftoppers as it lies on a frictionless table. Force F1 has a magnitude of 6.00 N and acts at theta 1 = 30 degree . Force F2 has a magnitude of 7.00 N and acts at theta 2 = 30 degree Determine the third force, in unit vector notation, acting on the blouse if it has the following velocities A sphere of mass 3.00 g is suspended from a cord. A steady horizontal breeze pushes the sphere so that the cord makes a constant angle of 28.0 degree with the vertical. Two paint buckets, each having a mass of 3.2 kg. are suspenced from cords as shown. The weight of eacft cord is 2.2 N. The buckets are pulled upward By the top cord causing them to accelerate at 1.25 m/s2. A Block is given an initial speed of 4.75 m/s up an 18 degree plane. An object is hang ng by a string from my rearview mirror. While acceleratng at a constant rate from rest to 18.7 m/s in 4.0 s. I notice that the object swings Back making an angle theta with the vertical. For the masses depicted in the figure, mA = 2.00 kg. mB= 1.00 kg. and theta = 23.0 degree . All surfaces involved are frictionless. For the system in problem 10. determine the mass mA needed to keep the system at rest if mass mB = 1.00 kg.
