Question
A cannon is rigidly attached to a carriage, which can move along horizontal rails, but is connected to a post by a large spring, initially unstretched and with force constant k = 2.00 × 104 N/m, as in Figure P6.67. The cannon fires a 200-kg projectile at a velocity of 125 m/s directed 45.0° above the horizontal. (a) If the mass of the cannon and its carriage is 5 000 kg, find the recoil speed of the cannon. (b) Determine the maximum extension of the spring. (c) Find the maximum force the spring exerts on the carriage. (d) Consider the system consisting of the cannon, the carriage, and the shell. Is the momentum of this system conserved during the firing? Why or why not?

- A tennis ball of mass 0.0646 kg is served. It strikes the ground with a velocity of 52.4 m/s (117 mi/h) at an angle of 21.3° below the horizontal. Just after the bounce it is moving at 48.4 m/s at an angle of 17.9° above the horizontal. If the interaction with the ground lasts 0.0712 s, what average force did the ground exert on the ball?arrow_forwardYou wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 50.1 kg. You pick up an object and drop it from rest, starting at a height of 1.97 meters above the floor, and it hits the floor 0.380 seconds later. You can ignore air resistance. Based on the outcome of this experiment, when you step on the scale provided for you, what weight will it register for your body? 684 N 911 N 1,367 N 491.5 Narrow_forwardRadical Albertan separatists are driving a tank at a constant speed of 10 m/s up a 45 degree mountain slope, in a vain attempt to invade British Columbia. Pursued by the Mounties, the tank fires a 10 kg watermelon, with muzzle velocity 25 m/s, back along its path. Ignore the distance from the muzzle to the slope. If the gun barrel is pointed 20 degrees above the horizontal as shown, how far is the melon from the tank (which keeps moving) when it finally strikes the slope below? Answer in m.arrow_forward

If the ball is in contact with the bat for a time of 1.27 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction.

A steel ball of mass 0.500 kg is fastened to a cord that is 70.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal (see figure below). At the bottom of its path, the ball strikes a 2.50 kg steel block initially at rest on a frictionless surface. The collision is elastic. a) Find speed of the ball just before impact. b) Find the speed of the block just after impact.arrow_forward

- A delivery person carries a stack of three boxes labeled 1, 2, and 3. Box 3 is on the bottom of the stack, and box 1 is on the top. The masses of boxes 1, 2, and 3 are m = 3.5 kg, m2 = 4.5 kg, and m3 = 8.0 kg, respectively. The delivery person places the stack of boxes on an elevator floor, which then accelerates upward with a magnitude of a = 0.90 m/s?. Assume that the positive direction is up.
