A 0.17- kg hockey puck is sliding to left with a speed of 15 m/s when it is hit by a hockey stick. If the puck is in contact with the stick for 0.15 s and it rebounds with a speed of 32 m/s, what was the average force exerted by the hockey stick on the puck? Assume the amount of friction or air resistance acting on the puck is negligible. (a) Fav = 2.89 N (b) Fav = 7.99 N (c) Fav = 19.3 N (d) Fav = 53.3 N (e) Fav = 313 N

P2. A hockey puck of mass 0.2 kg is travelling to the left with a velocity of v1 when it is struck by a hockey stick and given a velocity of v2 as shown. a) Draw the impulse-momentum diagram of the puck at this instant. b) Determine the magnitude of the net impulse exerted by the hockey stick on the puck. c) Determine the magnitude of the net force exerted by the hockey stick on the puck if the interaction occurs in 0.002 s. Note: In solving the problem, take v1 and v2 as

A 1.40−kg object slides to the right on a surface having a coefficient of kinetic friction 0.250 (Figure a). The object has a speed of v1 = 3.30 m/s when it makes contact with a light spring (Figure b) that has a force constant of 50.0 N/m. The object comes to rest after the spring has been compressed a distance d (Figure c). The object is then forced toward the left by the spring (Figure d) and continues to move in that direction beyond the spring's unstretched position. Finally, the object comes to rest a distance D to the left of the unstretched spring (Figure e). (a) Find the distance of compression d (in m). m (b) Find the speed v (in m/s) at the unstretched position when the object is moving to the left (Figure d). m/s (c) Find the distance D (in m) where the object comes to rest. m (d) What If? If the object becomes attached securely to the end of the spring when it makes contact, what is the new value of the distance D (in m) at which the object will come to rest after moving to the left? m
