- During that Laboratory, you found that impulse could also be related to motion in a certain way. Relate that simple mathematical relationship here. You also found a relationship between pairs of forces in certain situation. restate that relationship here. put these Results together to draw a general conclusion comparing the motion of two objects before and after a collision. You should be able to find a quantity, which will remain changed in a collision. Be sure to justify your reasoning. (Images of the lab mentioned).(b) What is the change in mechanical energy of the car-truck system in the collision? -9045.75 -9240 JAn oatmeal cookie is dropped on the floor. Is this an inelastic collision? Why or why not? It is because the cookie and floor can be considered one object. It is because the cookie and floor are stuck together. It is not because there is not momentum involved. It is not because the cookie and floor do not move away together as a unit.
- A 1500 kg car traveling to the north is slowed down uniformly from initial velocity of 20 m/s by a 6000 N braking force acting opposite the car’s motion. Use the impulse-momentum theorem to answer the following questions What is the car’s velocity after 2.00 s? How far does the car move during 2.00 s? How long does it take the car to come to a complete stop?When some cars are advertised, they quote a "stopping distance" from some speed to zero. The mass of the car and this value of "some speed" give a measure of initial motion, but we aren't necessarily told the mass. Using the stopping distance, one can directly calculate what physical quantity provided by the brakes? A impulse B chemical potential energy C power D kinetic energy E force F velocity G work H acceleration I massYou push a box of mass 21.4 kg with your car up to an icy hill slope of irregular shape to a height 5.1 m. The box has a speed 13.3 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before elastically colliding with a smaller box of mass 14 kg. The boxes then fall off a sheer cliff individually to the ground (with no drag). (a) How far from the cliff does the heavier box hit the ground? (b) What is the direction of motion of the heavier box as it hits the ground? = ŷ + 2 (c) How far from the cliff does the lighter box hit the ground? (d) What is the direction of motion of the lighter box as it hits the ground? W = ŷ + 2
- a 600 gram banana sliding north on a frictionless table at 2.5 meters per second bounces of a 400 gram kiwi fruit that is initially at rest , after colliding the banana continues moving north at 0.5 meters per second. At the North edge of the track is a frictionless inclined ramp which the kiwi fruit slides up to then the kiwi comes back down the ramp , without losing energy , and will now be moving south , the kiwi will catch up and hit the banana again. How much momentum did the kiwi have just before the sticky collision ? how much just after ? how much did the kiwis momentum change ?Consider the head-on collision of two identical bowling balls, each with mass 5 kg (see figure). Ball A with velocity v = m/s strikes ball B, which was at rest. Then ball A stops and ball B moves with the same velocity v that ball A had initially. M M В Initially at rest Initial state (before collision) Final state (after collision) M M B Now at rest (a) Choose a system consisting only of ball A. What is the momentum change of the system during the collision? Apsystem = kg • m/s What is the momentum change of the surroundings? Apsurroundings = kg • m/s (b) Choose a system consisting only of ball B. What is the momentum change of the system during the collision? Apsystem = kg · m/s What is the momentum change of the surroundings? Apsurroundings = kg · m/s (c) Choose a system consisting of both balls. What is the momentum change of the system during the collision? APsystem = kg · m/s What is the momentum change of the surroundings? Apsurroundings = kg • m/sa 600 gram banana sliding north on a frictionless table at 2.5 meters per second bounces of a 400 gram kiwi fruit that is initially at rest , after colliding the banana continues moving north at 0.5 meters per second. At the North edge of the track is a frictionless inclined ramp which the kiwi fruit slides up to then the kiwi comes back down the ramp , without losing energy , and will now be moving south , the kiwi will catch up and hit the banana again. If the last collision took 20 milliseconds , what was the average force exerted by the banana on the kiwi during the collision (magnitude and direction ) ? by the kiwi on the banana?
