Our friend Wile E. Coyote (SuperGenius) has developed another secret yet incredibly cunning plan to catch the Road Runner. The plan hinges upon the proper placement of his new cme^ TM Mobile Large Spherical Projectile Launch Apparatus ... in other words, a really big cannon on wheels. Our hero pushes the 2120 kg cannon from rest to a speed of 8.75 m/s over a horizontal surface with a constant horizontal force. During this time, the cannon moves a whopping distance of 48 meters. Neglecting any friction between the cannon and the surface, determine: (a) The work done by Wile E. Coyote ; (b) The constant horizontal force exerted on the cannon .

An adapted golf device attaches to a wheelchair to help people with mobility impairments play putt-putt. The stationary frame OD is attached to the wheelchair, and a club holder OB is attached to the pin at O. Holder OB is 6 in. long and weighs 8 oz, and the distance between O and D is x = 1 ft. The putter shaft has a length of L = 36 in. and weighs 10 oz, while the putter head at A weighs 12 oz. Knowing that the 1-lb/in. spring between D and B is unstretched when 0 = 90° and that the putter is released from rest at 0 = 0, determine the putter head speed when it hits the golf ball.
