The graph shows the potential energy U of a
system as one object in the system moves along the
x-axis and the rest of the system does not move.
Six evenly-spaced points along the x-axis are labeled.
At point H, the object is moving in the positive
x-direction and the mechanical energy of the system is
5.0 J. As the object moves, no energy enters or leaves
the system.
Which of the following describes the magnitude of
the momentum of the object in the first two
straight-line segments shown in the graph as the
object moves from point H to point J ?

- A 0.017-kg bullet is fired into a stationary block of wood of mass of 5.5 kg. The relative speed of the bullet with respect to the wood is zero after collision (The bullet becomes embedded on the block of wood). If the speed of the bullet before collision is 477 m/s, what is the kinetic energy of the bullet-plus-wood combination right after the collision? Assume no change in the potential energy of the system before and after the collision. Express your answer in two decimal places, in Joules.When no energy is lost to thermal modes in a collision, the coefficient of restitution is e = 1. This represents the ideal golfing equipment. The legal maximum is e = 0.83. A 200-g clubhead moving at 88 mph strikes a golf ball. The mass of the golf ball is 45 g. Calculate the total energy of the system just before the collision. Round the final answer to one decimal place.Box 1 (with mass m = 8.4 kg) is on a frictionless table moving with a velocity vo = 6.7 m/s. It collides with an identical box (let's call it box 2). The boxes stick together and launch horizontally off the table. What is the kinetic energy of the boxes when they land on the ground a distance H = 1.4 m below the table? H 1 Vo 2

(c) (a) (b) NumberT Unitšm/sA Ballistic Spring is like a Ballistic Pendulum, but it uses elastic potential energy instead of gravitational potential energy to measure the incident velocity of a projectile. Questions 4 and 5 refer to the Ballistic Spring shown below, where a projectile of mass m travelling with an initial velocity v impacts and travels through a block with mass M, emerging with a velocity , and causing the spring with constant k that is attached to the block to be compressed a distance d. m Vo Before M wwwww M Wowwwww AfterA locomotive of mass m= 1.134 × 10 kg uses 37.8 kW of power to accelerate at a constant rate for 15.0 s. a) The locomotive has an initial velocity of 0.500 m/s east. Calculate the locomotive’s speed after 15.0 s. After 15.0 s, the locomotive travels east at a constant speed and then collides and couples with atrain of four cars. Each of the cars has half the mass of the locomotive. Before the collision, thetrain was travelling east at 1.60 m/s.

Us/Um = [ΠΙ ΑΣΦ ?In this question you will use an energy approach to determine how the mass of a spring affects its motion. Normally we assume the spring has zero mass. But if we realize real springs have mass we can find the contribution to the kinetic energy of the system due to the motion of the spring. What makes this hard is that different parts of the spring move at different velocities. So, we must use a little calculus to find the result.Consider a vertical spring of mass m that has a mass M attached at its end. Let the position of the mass at the end of the spring relative to the point of attachment be given by Y and its velocity be given by V. a) What is the velocity of a small segment of the spring at the point of attachment? b) What is the velocity of a small segment of the spring right next to the moving mass? c) What is the velocity of a small segment of the spring that is exactly halfway between the top and the bottom? d) Now let the mass of the spring be m and…
