As shown in the figure, two boxes of mass and are connected by an essentially massless, non-elastic wire passing over a light, frictionless pulley. The box of mass m, is released from rest at height h above the table. Use the isolated system model to answer the following. (We assume m, > m,. Use any variable or symbol stated above along with the following as necessary: g.) (a) Determine the speed of m, just as m, hits the table. v= 5.77 Since the only force acting is the conservative force of gravity, mechanical energy is conserved. Write a statement of conservation of energy and the expressions for the change in kinetic energy and the change in gravitational potential energy. Combine these three expressions and solve for the speed in terms of known quantities. Note that you want the speed and not the velocity. (b) Find the maximum height above the table to which m, rises. hmax = 6.66 The maximum height is the distance h plus Ah the distance m, travels upward after m, lands on the…
A firework explodes into three pieces as shown in the diagram below. Now that you have set up the equation for the x and y components of the final momentum of the firework, let's do some physics! Given: The initial firework had a mass of 9.0 kg and was launched at vi = 110 m/s vertically straight up. The firework explodes into three pieces of equal mass 3.0 kg. The angles θ1 = θ3 = 20 ∘. Speed v1 = 100 m/s. What is the speed v2? Note: the angles shown for mass m1 and mass m3 are relative to the horizontal x axis. Mass m2 is moving straight up (y axis).

In order to answer this question, follow the steps provided and remember that the total initial momentum of the system must equal the total final momentum. Also, remember that momentum and velocity are vector quantities so you must specify a negative sign if the motion is to the left. A green truck of mass 2500 kg travels to the right with a velocity vig = 3.7 m/s. The green truck approaches a red truck with mass 1460 kg that is traveling to the left with a velocity of vir = -3 m/s. The trucks collide and stick together after the collision. What is the final velocity, vf of the green-red truck system after the collision. (look at the figure/picture)(a) What was the initial momentum of the green truck before the collision?pgi = 9250 kg m/s(b) What was the initial momentum of the red truck before the collision?pri = -4380 kg m/s(c) What was the total initial momentum of the system of trucks?pTf = 4870 kg m/s (d) What must be the total final momentum of the system after the collision if…

In this problem, we will consider the following situation as depicted in the diagram: A block of mass m slides at a speed v along a horizontal smooth table. It next slides down a smooth ramp, descending a height h, and then slides along a horizontal rough floor, stopping eventually. Assume that the block slides slowly enough so that it does not lose contact with the supporting surfaces (table, ramp, or floor). You will analyze the motion of the block at different moments using the law of conservation of energy. A B y=0 C a. Which word in the statement of this problem allows you to assume that the table is frictionless? b. Where (letter) would the block have the greatest gravitational potential energy? c. Where (location) would the block experience the greatest kinetic energy?

An acrobatic buccaneer swings from one rope to another in the rigging of a pirate ship. As she grasps the rope, her mass is m, 63.5 kg; knots on the rope make the rope's effective mass m, 1.50 kg. From the height %D she grabs the rope, she swings up a further distance of 1.50 m. Assuming that her collision with the rope is perfectly inelastic, answer the following questions: {Note: Treat as a ballistic pendulum problem!} mehanical a) Does the buccaneer's collision with the rope conserve her-kietie en- ergy? {Y/N?} b) Neglecting any energy losses due to friction, air drag, etc., determine the velocity of the buccaneer + rope system right after she grabs the rope in m/s. {Assume a closed system, thus Conservation of Energy} c) Is it possible to calculate the buccaneer's initial speed before she grabbed the rope from the information given? {Y/N?}

On a frictionless plane, a body with mass m1 hits with velocity v a second body at rest (mass m2) and connects to it. Subsequently, the composite body hits via a spring (spring constant k) a third body at rest (mass m3). a) Determine the speed v of the mass m1 such that m3 remains at rest, if the plane solely at the location of m3 is rough (coefficient of static friction μ0). b) Determine the speed of m3 after collision if the plane at the location of m3 is also frictionless.
Since a net force is equal to mass times acceleration, and a net force is also equal to the rate of change of momentum, then the rate of change of momentum must equal mass times acceleration. True False Consider a system of 2 objects, A and B. If the rate of change of momentum of the entire system (A and B together) is zero then The total momentum of the system must be zero. The total momentum of the system must be constant. The momentum of A must be constant, and the momentum of B must be constant. The total momentum of the system is conserved. the momentum of A must be zero, and the momentum of B must be zero. You don't have enough information to determine the momentum of A or the momentum of B.
