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

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

The figure here shows a plot of potential energy U versus position x of a 0.852 kg particle that can travel only along an x axis. (Nonconservative forces are not involved.) Three values are UA = 15.0 J, UB = 35.0 J and UC = 45.0 J. The particle is released at x = 4.50 m with an initial speed of 7.89 m/s, headed in the negative x direction. (a) If the particle can reach x = 1.00 m, what is its speed there, and if it cannot, what is its turning point? What are the (b) magnitude and (c) direction of the force on the particle as it begins to move to the left of x = 4.00 m ? Suppose, instead, the particle is headed in the positive x direction when it is released at x = 4.50 m at speed 7.89 m/s. (d) If the particle can reach x = 7.00 m, what is its speed there, and if it cannot, what is its turning point? What are the (e) magnitude and (f) direction of the force on the particle as it begins to move to the right of x = 5.00 m?
