A particle, of mass 100g, initially at rest at the origin, is acted upon by two forces F1 and F2 , (in the X–Y plane), directed as shown, for 10s. The coordinates of the particle, at t = 10s, in m would be (nearly)

(1) (22.8), (-9.14)

(2) (11.4), (-4.57)

(3) (11.4), (-4.57)

(4) (2.64), (-4.57)

(2) (11.4), (-4.57)

We have,

∴ Displacement, along X–axis, in 10 s

∴ The coordinates of the particle, at t = 10 s, are [(11.4 m),(-4.57)m]
