- 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?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 = ∆?/∆?Use the worked example above to help you solve this problem.
