A ball is attached to one end of a wire, the other end being fastened to the ceiling. The wire is held horizontal, and the ball is released from rest (see the drawing). It swings downward and strikes a block initially at rest on a horizontal frictionless surface. Air resistance is negligible, and the collision is elastic. The masses of the ball and block are, respectively, 1.7 kg and 2.5 kg, and the length of the wire is 1.23 m. Find the velocity (magnitude and direction) of the ball (a) just before the collision, and (b) just after the collision.

Two skateboarders, with masses m1 = 75.0 kg and m2 = 65.0 kg, simultaneously leave the opposite sides of a frictionless half-pipe at height h = 4.00 m as shown in Figure P11.49. Assume the skateboarders undergo a completely elastic head-on collision on the horizontal segment of the half-pipe. Treating the skateboarders as particles and assuming they dont fall off their skateboards, what is the height reached by each skateboarder after the collision? FIGURE P11.49
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 unstretchcd and with force constant k = 2.00 104 N/m, as shown in Figure P8.60.

(a) Assuming that 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, carriage, and projectile. Is the momentum of this system conserved during the firing? Why or why not?
4.12). As given in Figure 4, a thin uniform rod with mass M 3 kg and length I=0.4 m isfixed at one end and positioned horizontally. It swings after being released and collides with astationary block of mass m=1 kg at the lowest point of its swing. Then the block sticks to the lowerend of the rod and they keep swinging together until the rod makes an angle θ with the vertical. Findthe maximum value of θ that the rod block system can move up to. The moment of inertia of the rodabout its center is I rod=1/12mRod L^2
A student fires a 0.07 kg arrow at an object with mass m that is initially at rest on a frictionless surface. The speed of the arrow before the collision is 90 m/s.The speed when the arrow emerges from the object is v. What is the resulting velocity of the object? Let m=6.1 kg and v=0.78 m/s b) Is the collision between the arrow and the object elastic or inelastic?
An object of mass m1=2 kg moving with velocity 12 m/s, collides head-on with an object whose mass is m2=6 kg and velocity is 1 m/s. Given that the collision is elastic, what are the final velocities of the two objects. Neglect friction.
A 9.50-g bullet, moving horizontally withan initial speed v0, embeds itself in a 1.45-kg pendulum bob that isinitially at rest. The length of the pendulum is L = 0.745 m. Afterthe collision, the pendulum swings to one side and comes to restwhen it has gained a vertical height of 12.4 cm.

On a frictionless table, a 0.56 kg glob of clay strikes a uniform 1.26 kg bar perpendicularly at a point 0.35 m from the center of the bar and sticks to it. If the bar is 1.06 m long and the clay is moving at 9.30 m/s before striking the bar, what is the final speed of the center of mass?
A cannon of mass 5.12 x 10^3 kg is rigidly bolted to the earth so it can recoil only by a negligible amount. The cannon fires a 81.1-kg shell horizontally with an initial velocity of 549 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?
If a cart of mass 350 grams moving at speed of 4.5 m/s hits an end-stop and rebounds at a speed of 3.2 m/s, what is the change in momentum, in units of kg.m/s? A cart has the rubber bumper attached to the force sensor, and it moves and collides with an end-stop. In the collision, it suffers a change in momentum = 4.05 kg.m/s, and the time during which the collision takes place is 0.182 seconds. Calculate the average force applied on the cart by the bumper, in newtons.
A bullet of mass 0.0366kg and an initial speed of 353m/s is fired through a block of material with a thickness of 0.435m. The average force exerted on the bullet as it passes through the block has a magnitude of 1439N. What is the speed of the bullet, in meters per second, after passing through the block? The block is firmly fixed in place, so it does not move from its initial position
