Initially, ball 1 rests on an incline of height h, and ball 2 rests on an incline of height h/2 as shown in the figure below. They are released from rest simultaneously and collide elastically in the trough of the track. If m2 = 9m1, m1 = 0.049 kg, and h = 0.66 m, what is the velocity of each ball after the collision? (Assume the balls slide but do not roll. Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) V1f = m/s? V2f = m/s?
Particle A of mass m, initial velocity 20i (m/s) has a collision with a stationary particle B of mass 2m. After collision, VA(final)=10i+5j (m/s) I need help understanding how does the i and j effect the formula for collision problems? I know the usual collision probleam steps but don't understand how this would effect the steps to solve the questions asked from this scenerio such as finding VB(final) if the system linear momentum is conserved in both directions. or calculating what the velocities of center of the system are before and after collision?
Far in space, where gravity is negligible, a 465 kgkg rocket traveling at 75.0 m/sm/s fires its engines. The figure (Figure 1) shows the thrust force as a function of time. The mass lost by the rocket during these 30 ss is negligible. What impulse does the engine impart to the rocket? Express your answer as an integer and include the appropriate units. At what time does the rocket reach its maximum speed? Express your answer to three significant figures and include the appropriate units.

A firework explodes into three pieces as shown in the diagram below. Now that you have set up the equation for the x and y components of the final momentum of the firework, let's do some physics! Given: ∙∙ The initial firework had a mass of 9.0 kg and was launched at vi = 50 m/s vertically straight up. ∙∙ The firework explodes into three pieces of equal mass 3.0 kg. The angles θ1 = θ3 = 40 ∘. ∙∙ Speed v1 = 100 m/s. What is the speed v2? Note: the angles shown for mass m1 and mass m3 are relative to the horizontal x-axis. Mass m2 is moving straight up (y-axis).

A batsman playing cricket receives a ball of mass 160 g travelling at 12 ms−1 at an angle of 100 to the horizontal (i.e. to the ground) on his off stump side and returns it on the same side at 10 ms−1 at an angle of 500 to the incoming trajectory as indicated in the following diagram: (a) What impulse did the batsman apply to the ball? (b) Given the duration of the ball and bat contact was 0.002s what was the mean force applied at contact?
A container explodes and breaks into three fragments that fly off in one plane, indirections that make equal angles apart from one another. The resulting fragments have a massratio 1:5:1. What kind of process is this? Show the pictorial representation of the system (i.e., showthe vector momenta), and mark the known and unknown quantities that characterize this system. Show that the speeds of the first and third fragments must be equal. If the first piece flies off with a speed of 10.2 m/s, what is the speed of the second fragment?
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?

********PLEASE ONLY ANSWER PART D AND E******* Starting with an initial speed of 5.38 m/s at a height of 0.380 m, a 1.87-kg ball swings downward and strikes a 5.13-kg ball that is at rest, as the drawing shows. (a) Using the principle of conservation of mechanical energy, find the speed of the 1.87-kg ball just before impact. This value is 6.03 m/s (b) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 1.87-kg ball just after the collision. This value is -2.01 m/s (c) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 5.13-kg ball just after the collision. This value is 3.22 m/s (d) How high does the 1.87-kg ball swing after the collision, ignoring air resistance? (e) How high does the 5.13-kg ball swing after the collision, ignoring air resistance? I just need d and e answered please! Thank you.
can you please solve both questions they are asking in a piece of paper please. theres also another question : here is What is the magnitude of the larger marble's velocity after the collision?
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.
