A thin uniform bar lies on a frictionless surface and is free to move in any way on thesurface. Its mass is 0.16 kg and length 3 metres. Two particles each of mass 0.08 kgare moving on the same surface and towards the bar in a direction perpendicular to thebar, one with a velocity 10 m/s and the other with 6 m/s as shown in Figure. The firstparticle strikes the bar at A and the other at the point B. The points A and B are atdistance 0.5 m from centre of the bar. The particle strike the bar at the same instant oftime and stick to the bar on collision. Calculate the loss of kinetic energy of the systemin the above collisionprocess.10 m/s0.5 m3m6 m/s0.5 m

Tarzan grabs a vine, which is initially horizontal, and attempts to swing to the ground. Tarzan weighs 890 N and the breaking strength of the vine he knows is 1780 N. A Tarzan swings he is surprised to find that the vine breaks at a certain angle theta. Find theta.
A pendulum consists of a 1.7-kg block hanging on a 2.5-m length string. A 0.02-kg bullet moving with a horizontal velocity of 686 m/s strikes, passes through, and emerges from the block (initially at rest) with a horizontal velocity of 346 m/s. To what maximum height above its initial position will the block swing? Write your answer in meters.
A ball of mass 0.45 kg is fired with velocity 120 m/s into the barrel of a spring gun of mass 2.0 kg initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring. No energy is lost to friction. What fraction of the ball's initial kinetic energy is stored in the spring?
A ball is attached to one end of a wire, the other end being fastened to the ceiling. The wire is held horizontal, and the ball is released from rest (see the drawing). It swings downward and strikes a block initially at rest on a horizontal frictionless surface. Air resistance is negligible, and the collision is elastic. The masses of the ball and block are, respectively, 1.7 kg and 2.5 kg, and the length of the wire is 1.36 m. Find the velocity (magnitude and direction) of the ball just after the collision.
Apollo and Artemis are playing on the teeter‑totter in their school's playground. They both have approximately the same mass. They are sitting on either side of the teeter‑totter at about the same distance from the teeter‑totter's pivot point. The teeter‑totter is going up and down and they are having a great time! Mercury, the new kid in school, wanders by. Since they are very friendly kids, Apollo and Artemis ask Mercury to join them. Mercury joins Apollo on his side of the teeter‑totter and sits next to him. What should Artemis do in order to keep the fun going? 1)Move farther from the teeter‑totter's pivot point in order to balance out the new smaller torque provided by Mercury and Apollo. 2)Move closer to the teeter‑totter's pivot point in order to balance out the new larger torque provided by Mercury and Apollo. 3)Move farther from the teeter‑totter's pivot point in order to balance out the new larger torque provided by Mercury and Apollo. 4)Move closer to the…
A package of mass 7 kg sits at the equator of an airless asteroid of mass 4.0 1020 kg and radius 5.9 105 m. We want to launch the package in such a way that it will never come back, and when it is very far from the asteroid it will be traveling with speed 188 m/s. We have a large and powerful spring whose stiffness is 2.1 105 N/m. How much must we compress the spring?
In the figure, block 2 (mass 1.10 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 216 N/m. The other end of the spring is fixed to a wall. Block 1 (mass 1.80 kg), traveling at speed v1 = 5.90 m/s, collides with block 2, and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?
A small ball of mass mb = 0.050 kg is projected into a pendulum of mass Mp = 0.200 kg in a ballistic pendulum experiment. How fast does the ball need to go in order to get the pendulum to swing up to a height of h = 0.25 m above its original position? 2.21 m/s 0.111 m/s 11.1 m/s 0.553 m/s
A 1.5-kg block is attached to the end of a 1.9-m string to form a pendulum. The pendulum is released from rest when the string is horizontal. At the lowest point of its swing when it is moving horizontally, the block is hit by a 0.02-kg bullet moving horizontally in the opposite direction. The bullet remains in the block and causes the block to come to rest at the low point of its swing. What was the magnitude of the bullet's velocity just before hitting the block?
James decides to use a ball tied to stiff rod to take out the Road Runner. He first needs to test this idea out on a small scale. A steel ball of mass 0.500 kg is fastened to a cord that is 70.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal (see figure below). At the bottom of its path, the ball strikes a 2.50 kg steel block initially at rest on a frictionless surface. The collision is elastic. a) Find speed of the ball just before impact. b) Find the speed of the block just after impact.
A 4,600 kg open train car is rolling on frictionless rails at 21.1 m/s when it starts pouring rain. A while later the car's speed is 19.5 m/s. What mass of water has collected in the car? Provide your answer in appropriate units of meters (m), seconds (s), kilograms (kg), radians (rad) or combinations thereof, such as m/s or m/s^2. Use at least three significant figures in your answer, do not use scientific notation. Using more significant figures will not be considered incorrect; using fewer may lead to errors due to rounding.
An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion, away from the space station. The astronaut has a mass of ma = 124 kg and the bag of tools has a mass of m = 13.0 kg. If the astronaut is moving away from the space station at Vj = 1.20 m/s initially, what is the minimum final speed vpf of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever? Ub.f = m/s
