A particle with mass of 2.95 kg is acted on by a force F acting in the x-direction. If the magnitude of the force varies in time as shown in the figure below, determine the following. Fx (N) 8 6 4 1 2 (a) impulse of the force (in kg. m/s) kg m/s 3 4 5 t (s) (b) final velocity of the particle (in m/s) if it is initially at rest m/s (c) Find the final velocity of the particle (in m/s) if it is initially moving along the x-axis with a velocity of -1.70 m/s. m/s
