An object with mass m = 10 kg is acted upon by two forces in the xy plane (assume z=0). The first force has magnitude |F₁| = 20 N and 0x = 90°. The second force has magnitude |F₂| = 30 N and 0x = -30°. a. Write out the two force vectors by components. Find the net force acting on the mass. b. The mass starts from rest at the origin. What is the momentum after 5 seconds? Write out the components, magnitude, and direction for momentum. c. Find the position of the mass at t = 5 s. X 1 10 kg Ꮎ F2
