Question

a particle of m=5kg is momentarily at rest at x=0 at t=0 .it is acted upon by two forces f1 ^arrow and f2^arrow . f^arrow = 70jcap N the direction and magnitude of the f2^arrow are unknown . the particle experiences a constant acceleration a^arrow in the direction as shown in figure neglect gravity
(1) find the missing force f2^arrow
(2) what is the velocity vector of the particle at t=10s?
(3) what third force f3^arrow is required to make the acceleration of the particle zero? either give magnitude and direction of f3^arrow or its components

Answer 1

Dear Preeti a particle and all Idk but please put this question in physics corner
