Below is a diagram of the forces acting on a 100 gram ball that is placed on a horizontal frictionless surface. All the forces are parallel to the surface. F1 has a magnitude of 2 N, F2 has a magnitude of 3 N, and F1 and F2 are perpendicular to one another. Please, find the magnitude of force F3 if the ball has acceleration of 0.2 m/s2 in the direction of F1 force.

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
