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).
Momentum and impulse. This question would like to find the net force-thats what we are looking for. Only the net force is happening a guy throws one box every 6 seconds and there will be recoil. What we want to do is find the net force is while he throws the boxes (during the time he throws them).
Consider the collision of a karate expert's hand with a concrete block. Based on the graphs in the figure below, the initial downward velocity of the fist with mass 0.50 kg is about −12.5 m/s and the collision time is approximately 25 ms. Find the impulse (in kg · m/s) and the average force (in N) exerted on the block by the fist during the collision. (Indicate the direction with the signs of your answers.) impulse...... kg · m/s average force....... N

In lab you investigated collisions between carts on a low-friction track. Imagine initially one of the carts (m1 = 250g) moved with a speed of vi = 3m/s to the right and the other (m2 = 500g) was initially at rest. (Here, as always, please show your work and explain your answers using the laws of physics. In other words, don't just rely on intuition and experience.) (a) If this was a perfectly elastic collision, what would you expect the velocities of the carts to be after the collision? (b) What was the velocity of the center of mass before the collision? What is the velocity of the center of mass after the collision? (Explain!)
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: _________________________
