A cannon is rigidly attached to a carriage, which can movealong horizontal rails, but is connected to a post by a large spring, initially unstretched and with force constant k = 2.00 x 104 N/m, as inFigure P6.75. The cannon fires a 2.00 x 102-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 5.00 x 103-kg, find therecoil speed of the cannon. (b) Determine the maximum extensionof the spring. (c) Find the maximum force the spring exertson the carriage. (d) Consider the system consisting of the cannon,the carriage, and the shell. Is the momentum of this systemconserved during the firing? Why or why not?
A ball with a mass of 0.45 kg is initially at rest on the ground. When the ball is hit by a mallet, the average force exerted on it is 270 N. If the ball's speed after being struck is 5.4 m/s, for what amount of time was the mallet in contact with the ball?
A baseball (m = 152 g) approaches a bat horizontally at a speed of 43.6 m/s (97.6 mi/h) and is hit straight back at a speed of 53.8 m/s (120 mi/h). If the ball is in contact with the bat for a time of 1.03 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.

Att = 0, force F-=(6.30i +6.10j +3.50k)N begins to act on a 2.90 kg particle with an initial speed of 3.60 m/s. What is the particle's speed when its displacement from the initial point is d = (1.60î + 2.80j + 7.80k) m ?
A baseball (m = 148 g) approaches a bat horizontally at a speed of 40.7 m/s (91.1 mi/h) and is hit straight back at a speed of 51.6 m/s (115 mi/h). If the ball is in contact with the bat for a time of 1.45 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.
The two masses in the Atwood's machine shown in the figure have an initial speed of v = 0.15 m/s , and m2 is moving upward.How high does m2 rise above its initial position before momentarily coming to rest, given that m1 = 3.3 kg and m2 = 4.4 kg?
In an intersection, a bus moving at (100i) m/s and a truck moving at (200j) m/s collided with each other. Assuming that the two objects have the same mass, what would be their final speed together? Note: i and j are unit vectors CHOICES: - 300 m/s - 173.21 m/s - 100 m/s - 223.61 m/s
An object with mass m1 = 1kg moving to the right at a speed of 4m / s collides with a spring attached to a second block of mass m2 = 2kg moving left at 2m / s on a horizontal plane without friction as shown in the figure. The force constant of the spring is 105N / m and find the compression amount of the spring when the mass m1 moves at a speed of 3m / s to the right.
A boy who is, 73 kg, is training on Dagobah. He runs up a incline for 10 m with an average velocity of 6 mph. He then performs the same run with Yoda on his back in 4.31 s. Assuming he makes the second run with equivalent power and that the acceleration due to gravity is the same as earth, what is Yoda's mass? 1 mi = 1.6 km A. 11 kg B. 13 kg C. 116 kg D. 189 kg
A skater of mass 81.0 kg initially moves in a straight line at a speed of 5.10 m/s. The skater approaches a child of mass 43.5 kg, whom he lifts on his shoulders. Assuming there are no external horizontal forces, what is the skater's final velocity?
The mass of a particular skateboard plus its rider is ms=78.6kg, and the skateboarder is holding a book with mass mb=3.07kg. Initially at rest, the skateboarder tosses the textbook with a velocity of vb=2.74m/s at an angle θ=24.3∘ above the horizontal, and the book is caught by a friend. Calculate the magnitude, in meters per second, of the velocity of the student. What is the magnitude, in newton seconds, of the momentum, pE, which was transferred to the the Earth during the time the book was being thrown?
A block of mass 2.60 kg slides down a 30.0 incline which is 3.60 mm high. At the bottom, it strikes a block of mass 6.60 kg which is at rest on a horizontal surface.
