The hammer throw is a track and field event in which a 8.11-kg ball (the "hammer"), starting from rest, is whirled around in a circle several times and released. It then moves upward on the familiar curving path of projectile motion. In one throw, the hammer is given a speed of 32.2 m/s. For comparison, a .22 caliber bullet has a mass of about 2.48 g and, starting from rest, exits the barrel of a gun with a speed of 447 m/s. Determine the work done to launch the motion of (a) the hammer and (b) the bullet. (a) Number i (b) Number i Units Units

- Help needed.A railroad cart with a mass of m₁ = 12.6 t is at rest at the top of an h = 10.3 m high hump yard hill. m m₂ h After it is pushed very slowly over the edge, it starts to roll down. At the bottom it hits another cart originally at rest with a mass of m₂ = 18.6 t. The bumper mechanism locks the two carts together. What is the final common speed of the two carts? (Neglect losses due to rolling friction of the carts. The letter t stands for metric ton in the SI system.)Gayle runs at a speed of 3.65 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 48.0 kg, the sled has a mass of 5.45 kg and her brother has a mass of 30.0 kg. m/s

After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 18.0 m? Gayle's mass is 50.0 kg, the sled has a mass of 5.00 kg and her brother has a mass of 30.0 kg. m/sAn outlaw cuts loose a wagon with two boxes of gold, of total mass 300 kg, when the wagon is at rest 50 m up a 6.0° slope. The outlaw plans to have the wagon roll down the slope and across the level ground, and then fall into a canyon where his accomplices wait. But in a tree 40 m from the canyon’s cliff wait the Lone Ranger (mass 75.0 kg) and Tonto (mass 60.0 kg). They drop vertically into the wagon as it passes beneath them (Fig.). (a) If they require 5.0 s to grab the gold and jump out, will they make it before the wagon goes over the cliff? The wagon rolls with negligible friction. (b) When the two heroes drop into the wagon, is the kinetic energy of the system of heroes plus wagon conserved? If not, does it increase or decrease, and by how much?
- A 30 kg box with a height of 0.230 meters is on top of a 0.5-meter-high table and is initially at rest. A 5kg projectile having a speed of 20 m/s was launched at the horizontal ground, 6.972 meters (horizontal distance) away from the nearest vertical wall of the box. When the projectile hit the vertical side of the box, it rebound at a speed of -11.143 m/s and the box developed a speed of 5.140 m/s. At what angle was the projectile launched?A person is crossing a bridge. The bridge is 3.2 meters long and is 25 kg. One side of the bridge rests on the ground while the other side of the bridge is elevated 25 degrees above the ground. The end of the bridge that is elevated is connected to a rope, which is attached to a overhanging section of a cliff. The person walking across is 62 kg, and walks three quarters of the way to the rope end of the bridge then stops. Please determine the magnitude of the force that the ground exerts on the bridge.

The rod is initially at rest in its equilibrium position when a ball of play dough, of mass mb, strikes the rod at its lower end and remains stuck to the rod. The sticky ball is thrown with an initial speed v0 at a 60 degree angle from the horizontal direction, and strikes the rod when it reaches the top of its trajectory, as shown in Fig.4. The acceleration due to gravity has magnitude g and air resistance is negligible. a. Determine the velocity of the ball of play dough right before it sticks to the rod. Use the x- y coordinate system defined in Fig.4. b. Determine the angular velocity of the rod+ball system right after the collision. Take counterclockwise as positive. c. - Establish the differential equation satisfied by the rod+ball system after the collision and determine the angular frequency of the system. You may assume that the small…
- You push a box of mass 21.4 kg with your car up to an icy hill slope of irregular shape to a height 5.1 m. The box has a speed 13.3 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before elastically colliding with a smaller box of mass 14 kg. The boxes then fall off a sheer cliff individually to the ground (with no drag). (a) How far from the cliff does the heavier box hit the ground? (b) What is the direction of motion of the heavier box as it hits the ground? = ŷ + 2 (c) How far from the cliff does the lighter box hit the ground?
