1. Two players kick a soccer ball at the same time at an angle of 115°. One of them kicks with a force of 130 N and the other with a force of 120N. The angle between the forces is 115°. Find the magnitude of the resultant force.

Four acrobats of mass 67.0 kg, 68.0 kg, 62.0 kg, and 55.0 kg form a human tower, with each acrobat standing on the shoulders of another acrobat. The 67.0-kg acrobat is at the bottom of the tower. (a) What is the normal force acting on the 67.0-kg acrobat? (Enter the magnitude only.) 2469.6 ✔N (b) If the area of each of the 67.0-kg acrobat's shoes is 500 cm2, what average pressure (not including atmospheric pressure) does the column of acrobats exert on the floor? 53686.96 X Your response differs from the correct answer by more than 100%. Pa (c) Will the pressure be the same if a different acrobat is on the bottom? Pressure will be the same since the total mass of acrobats remains the same

Three astronauts, propelled by jet backpacks, push and guide a 129 kg asteroid toward a processing dock, exerting the forces shown in the figure, with F₁ = 35.0 N, F₂ = 53.0 N, F3 = 40.0 N, 0₁ = 30.0°, and 03 = 60.0°. What is the (a) magnitude and (b) angle (measured relative to the positive direction of the x-axis in the range of (-180°, 180°]) of the asteroid's acceleration? (a) Number (b) Number Units Units F3 F₂ X
