Given data The mass is m=0.46 kg The initial velocity is u=5.5 m/s The final velocity is v=0 m/s The distance travelled by the hammer is ∆x=1.25 cm (a) The equation of motion for the hammer is, v2=u2+2a∆x0 m/s2=5.5 m/s2+2a1.25×10-2 ma=-5.5 m/s221.23×10-2 m=-1210 m/s2 Here a is accleration of the hammer. Here negative sign indicates that the accleration is in the opposite direction of motion.Again the equation of motion for the hammer is v=u+at0 m/s=5.5 m/s+-1210 m/s2tt=5.5 m/s1210 m/s2=4.5454×10-3 s Here t is the duration of impact. Thus, the duration of the impact is 4.5454×10-3 s. (b) The average force is, Fa=mv-ut=0.46 kg0 m/s-5.5 m/s4.5454×10-3 s=-556.6 N Thus, the average force is -556.6 N. Here negative sign indicates that the force is in the opposite direction of motion.

The figure shows the view looking down onto an air hockey table. A puck collides with a stationary bar. The collision is completely inelastic.The bar has mass M = 1.44 kilograms and length L = 1.14 meters. The puck has mass m = 0.488 kilograms and is initially moving at vi = 6.83 perpendicular to the bar. The puck collides with the bar at a location of b = 0.505 meters from the center of the bar. Note that the size of the puck is negligible compared to the length of the bar. vf = 1.729. Calculate the angular speed (rad/s) about the center of mass of the puck-and-bar system just after the collision.
