A particle of mass 0.17 kg follows a trajectory with an initial speed of 12.5 m.s¹ and an initial angle of 0.5 radians from the i axis (toward j). Gravity accelerates the mass downward at -9.81i [m.s¯²] and a force of (10-0.1t)j [N] acts on the particle. F. Answer all questions to at least 3 significant figures. Enter your numerical answers in SI units but do not enter the units. What is the force acting on the mass toward i at 2.2 seconds? [N] When does the particle pass through u.i=0 [s] What is the j component of velocity at t=2.2 seconds? [m.s¯¹]
