Question

A force of magnitude Fx acting in the x-direction on a 1.95-kg particle varies in time as shown in the figure below. (a)Find the impulse of the force. kg ? m/s (b) Find the final velocity of the particle if it is initially at rest. m/s (c) Find the final velocity of the particle if it is initially moving along the x-axis with a velocity of -2.10 m/s. m/s

Explanation / Answer

impulse=f*dt so impulse is area under the curve=12 (b) impulse=change in momentum so final velocity=impulse/mass=6.153 m/s c. 8.253 m/s
