A cannon of mass 5.26 x 10³ kg is rigidly bolted to the earth so it can recoil only by a negligible amount. The cannon fires a 77.7-kg shell horizontally with an initial velocity of 587 m/s. Suppose the cannon is then unbolted from the earth, and no external force hinders its recoil. What would be the velocity of a shell fired from this loose cannon? (Hint: In both cases assume that the burning gunpowder imparts the same kinetic energy to the system.)

While a disk with a mass of ma=5 kg travels at VA=4m/s speeds in the +x direction, it collides with another disk with a mass of mp=2 kg on its way. After the collision, if disk A moves with a speed of V'A=2 m/s, making an angle of 0=37° degrees with the A coming direction, what is the velocity of disk B (V'B) after the collision? (sin53°=cos37°=0,8, sin37°=cos53°=0,6). B
During a circus act, a performer thrills the crowd by catching a cannon ball shot at him. The cannon ball has a mass of m1 = 8.5 kg and the horizontal component of its velocity is v = 8.25 m/s when the performer, of mass m2 = 70.5 kg, catches it. a)If the performer is on nearly frictionless roller skates, enter an expression for his recoil speed, in terms of the masses and initial speed. v' =
A steel ball of mass 0.870 kg is fastened to a cord that is 85.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure.

In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0235 kg and the mass of the pendulum is 0.250 kg, how high h will the pendulum swing if the marble has an initial speed of 5.65 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision. h = m
You have just planted a sturdy 2-m-tall palm tree in your front lawn for your mother’s birthday. Your brother kicks a 500g ball, which hits the top of the tree at a speed of 5 m/s and stays in contact with it for 10 ms. The ball falls to the ground near the base of the tree and the recoil of the tree is minimal. (a) What is the force on the tree? (b) The length of the sturdy section of the root is only 20 cm. Furthermore, the soil around the roots is loose and we can assume that an effective force is applied at the tip of the 20 cm length. What is the effective force exerted by the end of the tip of the root to keep the tree from toppling? Assume the tree will be uprooted rather than bend. (c) What could you have done to ensure that the tree does not uproot easily?
