- 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 = 50 m/s vertically straight up. ∙∙ The firework explodes into three pieces of equal mass 3.0 kg. The angles θ1 = θ3 = 40 ∘. ∙∙ 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).Particle A of mass m, initial velocity 20i (m/s) has a collision with a stationary particle B of mass 2m. After collision, VA(final)=10i+5j (m/s) I need help understanding how does the i and j effect the formula for collision problems? I know the usual collision probleam steps but don't understand how this would effect the steps to solve the questions asked from this scenerio such as finding VB(final) if the system linear momentum is conserved in both directions. or calculating what the velocities of center of the system are before and after collision?I did my lab for Momentum in Conservation in Momentum and I want to know What was the difference in momentum? Was momentum conserved? according to the pictures I posted below of the results.
- Three objects A, B, and C are moving as shown in (Figure 1). Assume that Va = 10.6 m/s , Vb = 10.0 m/s, and Vc = 4.00 m/s. Find the x component of the net momentum of the particles if we define the system to consist of A and C. Find the y component of the net momentum of the particles if we define the system to consist of A and C. Find the x component of the net momentum of the particles if we define the system to consist of B and C. Find the y component of the net momentum of the particles if we define the system to consist of B and C. Find the x component of the net momentum of the particles if we define the system to consist of all three objects. Find the y component of the net momentum of the particles if we define the system to consist of all three objects.Consider the before- and after-collision momentum vectors in the diagram below. Determine the magnitude and direction of the system momentum before and after the collision and identify whether or not momentum is conserved. Finally, determine the magnitude and direction of the net external impulse encountered by the system during the collision. (Hint: Velocity and masses are give) System Momentum Before Collision: _________________________ System Momentum After Collision: _________________________ Is momentum conserved? _________________________ Net External Impulse During Collision: _________________________Shows a cube at rest and a small object heading toward it. (a) Describe the directions (angle θ1) at which the small object can emerge after colliding elastically with the cube. How does θ1 depend on b, the so-called impact parameter? Ignore any effects that might be due to rotation after the collision, and assume that the cube is much more massive than the small object. (b) Answer the same questions if the small object instead collides with a massive sphere.
- Josh and Jayvee throw a ball toward one another with masses of 1.4kg ad 2.6kg, moving at 5.7 m/s and 3.7 m/s, respectively. If the balls experience elastic collision, solve the following: a. Illustrate a diagram of the moment of collision. b. Compute for the momentum before the collision of the ball thrown by Josh. c. Compute for the momentum before the collision of the ball thrown by Jayvee d. What are the velocities of the two balls after the collisionUse the worked example above to help you solve this problem. A rocket has a total mass of 1.04 x 105 kg and a burnout mass of 1.11 x 104 kg, including engines, shell and payload. The rocket blasts off from Earth and exhausts all its fuel in 3.84 min, burning the fuel at a steady rate with an exhaust velocity of ve= 4.83 x 103 m/s. (a) If air friction and gravity are neglected, what is the speed of the rocket at burnout?(b) What thrust does the engine develop at liftoff?(c) What is the initial acceleration of the rocket if gravity is not neglected?(d) Estimate the speed at burnout if gravity isn't neglected.Given 2 identical marbles each of mass M traveling together a speed V what is the total linear momentum of this 2 marble system? what is the total kinetic energy? If the 2 marbles from the previous question strike three stationary marbles (as in your previous tests), what is the total linear momentum of the marble(s) that are in motion after the collision? What is the total kinetic energy?
- Kindly provide given, and show complete answer. Draw the FBD if necessary A billiard ball moving at a speed of 2.2 m/s strikes an identical stationary ball a glancing blow. Afterthe collision one ball is found to be moving at a speed of 1.1 m/s in a direction making a 60◦ angle with the original line of motion.(a) Find the velocity of the other ball.(b) Can the collision be inelastic, given these dataIn the figure below, what is the velocity of the bullet and the block just after the collision? Notice that they stick together after the collision.This is a two-dimensional version of a conservation-of-momentum problem. Now we will have to keep track of both the x and y components of the momentum of each object in the system. (Figure 1) shows two chunks of ice sliding on the surface of a frictionless frozen pond. Chunk A, with mass mA=5.0kg, moves with initial velocity vA,i=2.0m/s parallel to the x axis. It collides with chunk B, which has mass mB=3.0kg and is initially at rest. After the collision, the velocity of A is found to be vA,f=1.0m/s in a direction at an angle α=30∘ with the initial direction (Figure 2). What is the final velocity of B (magnitude and direction)? PART A. b)If chunk B has an initial velocity of magnitude 1.6 m/s in the +y direction instead of being initially at rest, find the final magnitude of its velocity. c)Using Part A, find the final direction of the velocity.
