- Car A is moving to the right at 0.5m/s. Meanwhile, Car B, which is 6 meters to the right of car A is moving to the left at 0.25m/s. Looks like they’re going to have a head-on collision. Predict the location of the collision.The momentum of an isolated system is conserved O none of the given choices O only in elastic collisions O only if the objects have the same velocity O in both elastic and inelastic collisions O only in inelastic collisionsChoose the best answer: An object that is speeding up would have O a a negative momentum O b zero momentum O c an increasing momentum d. constant momentum O e a decreasing momentum a positive momentum
- Archerfish are one of the few fish that prey on land insects and other small animals. They do this by shooting a jet of water from their specialized mouths at an insect resting on a leaf or plant stem above the water (see photo). This often stuns the insect, causing it to fall into the water, where it can be eaten. In the drawing, an archerfish is shooting water toward an unsuspecting horsefly at rest on a blade of marsh grass above the surface of a pond. Use the information in the drawing to calculate how high (h) the horsefly is above the water. The initial velocity of the water (vo) is 3.2 m/s, and assume that the projected water reaches its maximum height above the pond's surface when it strikes the horsefly. to search Varren l'hotographic FOWL A O 1 10 OF 55°F Mostly cloudya 3kg red car travelling to the right at 5 m/s strikes a stationary 2kg blue car, locking the two of them together. what is the final velocity of the two cars?a)If Olaf catches the ball, with what speed vf do Olaf and the ball move afterward?

- Please help!! Urgent!! You are playing pool and decide to practice your ability to make trick shots. In this trick shot you are attempting to strike an object ball with the cue ball while the object ball is moving and make the shot. If the object ball is moving directly from you at a speed of 0.10 m/s and you strike the cue ball at 0.50 m/s directly in line with the object ball, then after the cue ball and object ball collide, how fast will they be moving apart relative to one another? Previous answer someone gave me was two answers and I only need one!! Please help!!Human reaction time is usually about 0.20 s. If your lab partner holds a ruler between your finger and thumb and releases it without warning, how far can you expect the ruler to fall before you catch it? The nearest value is:A motorcycle daredevil plans to ride up a 2.0-mm-high, 20∘∘ ramp, sail across a 10-mm-wide pool filled with hungry crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as he starts up the ramp. He is going 10.4 m/sm/s at that instant, and the rolling friction of his rubber tires (coefficient 0.02) is not negligible. Justify your answer by calculating the distance he travels through the air after leaving the end of the ramp. x =
