How would you find the velocity (and direction) of the cue ball after the collision? (answers are 2.58m/s at 45.1° South of East but I'm not sure on how to get those answers)
Step by step
Solved in 3 steps with 3 images
- Two billiard balls are at rest and touching each other on a pool table. The cue ball travels at 3.8 m/s along the line of symmetry between these balls and strikes them simultaneously. If the collision is elastic, what is the velocity of the three balls after the collision?A ball of mass 10 kg makes a head-on elastic collision with a second ball (at rest) and rebounds with a speed equal to 0.3 its original speed. What is the mass (in kg) of the second ball? (Could you please provide a step by step formula?)

- Use the worked example above to help you solve this problem. Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are v1i= +25.2 cm/s and v2i = −20.3 cm/s, what are the velocities of the balls after the collision? Assume friction and rotation are unimportant. (Indicate the direction with the sign of your answer.)Use the worked example above to help you solve this problem. A car with mass 1.40 x 103 kg traveling east at a speed of 29.4 m/s collides at an intersection with a 2.56 x 103 kg van traveling north at a speed of 18.3 m/s, as shown in the figure. Find the magnitude and direction of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision (that is, they stick together) and assuming that friction between the vehicles and the road can be neglected.Show the complete solution (in GRESA format), always include the SI units on your solution, express your answer in two decimal places and box your final answer. 1. Two carts collide head-on and then ricochet off each other in opposite directions on a frictionless surface. The first cart has a mass of 0.350 kg and an initial velocity of 1.50 m/s. The second cart has a mass of 0.500 kg and an initial velocity of 0.75 m/s. After the collision, the smaller cart recoils with a velocity of 4.0 m/s. What is the final velocity of bigger cart?
- Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. Ball A is moving upward along the y axis at Va = 2.5 m/s and ball B is moving to the right along the x axis with speed Vb= 3.9 m/s. After the collision, assumed elastic, ball B is moving along the positive y axis ( Figure 1). What is the final direction of ball A? Express your answer using two significant figures. Answer should be in degrees. 0 = ________ degrees clockwise from the +y directionA 4,700-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 2 m/s. What was the speed of the truck before the collision? Please include formulas & steps because I do not understand how to approach this question, thank you!Use the worked example above to help you solve this problem. A rocket has a total mass of 1.04 x 105 kg and a burnout mass of 1.11 x 104 kg, including engines, shell and payload. The rocket blasts off from Earth and exhausts all its fuel in 3.84 min, burning the fuel at a steady rate with an exhaust velocity of ve= 4.83 x 103 m/s. (a) If air friction and gravity are neglected, what is the speed of the rocket at burnout?(b) What thrust does the engine develop at liftoff?(c) What is the initial acceleration of the rocket if gravity is not neglected?(d) Estimate the speed at burnout if gravity isn't neglected.
