Check Your Understanding Notice that the mass of the air in the tank was neglected in the analysis and solution. How would the solution method changed if the air was included? How large difference do you think if would make in the final answer?
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?
For each run of your elastic and inelastic collision experiment, observe the initial momentum and the final momentum. Does your data indicate conservation of momentum? (NOTE: Please see the attached photos of the values of masses velocities, and momentum in order to answer the question.)
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?
A steel ball of mass 3 kg strikes a wall with a speed of 6.22 m/s at an angle of 60o with the surface. It bounces off with the same speed at an angle shown in figure. Assume that the collision lasts for 10.4ms. To determine the following (i) impulse ‘J’ experienced by the ball?(ii) average force ‘F’ exerted by the ball on the wall? Hint:Steps to find the Impulse and net force exerted by the ball:❖ Resolve the components and find ??? , ???❖ The ball has the same speed before and after bouncing from the wall, the momentum in the x direction remains the same and hence Pxi = Pxf. therefore ∆?? becomes zero ❖ The initial and final momentum in the y direction is changed and hence ∆?? = ?(??? − ???). Substitute ??? , ??? in the formula to determine ∆??❖ Calculate the impulse using the formula J = ∆? = ∆?? − ∆??❖ Find the force exerted by the ball through the formula F = ∆?/∆?
Hello can you help me solve this problem with complete solution and illustration? *A 40kg boy is sliding on a horizontal and frictionless surface with an initial momentum of 90J due east. When t=0, a force, a function of time, F=8.20t is applied to the boy due west. a) at what value of t will result in the momentum of the boy 60J due west? b) what is the acceleration of the boy at the time computed in letter a?
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.

How would you find the velocity of the cue ball after the collision? (Please include magnitude and direction). Also, would this be an elastic or inelastic collision?
Ball 1, with a mass of 100 g and traveling at 10 m/s, collides head-on with ball 2, which has a mass of 300 g and is initially at rest. What are the final velocities of each ball if the collision is (a) perfectly elastic? (b) perfectly inelastic?
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?
In the figure below, what is the velocity of the bullet and the block just after the collision? Notice that they stick together after the 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.
