Question

Two forces, vector F 1 = (7 î - 2 ĵ) N and vector F 2 = (5 î - 9 ĵ) N, act on a particle of mass 1.80 kg that is initially at rest at coordinates (-1.80 m, +3.80 m). (a) What are the components of the particle's velocity at t = 11.0 s? vector v = m/s (b) In what direction is the particle moving at t = 11.0 s? ° ( counterclockwise from the positive x axis) (c) What displacement does the particle undergo during the first 11.0 s? Δvector r = m (d) What are the coordinates of the particle at t = 11.0 s? x = m y = m
