After the collision the first mass has a velocity V1f. make a diagram of the initial momemtub vectors and final momentum vectors in a (x,y) plane. determine the final velocity of the second mass in (I J K) notation. determine the final velocity of the second mass in terms of speed and angle.

Determine the total impulse on the ball when it hits the floor. hi for the above question, i am able to obtain the answer using method 1 as shown in the picture. But my question is why is the velocity V2 that is going = 0 when computing the velocity V3 that is going upwards using the conservation of energy? in short, why does my method 2 not get the same V3 as my method 1arrow_forwardTwo objects collide head on in an elastic collision. Assume they have equal masses but unequal velocities, such that the one coming in from the right is moving at 6 m/s toward the left, and the one coming in from the left is moving at 2 m/s toward the right. After the collision, what is the velocity of the one that came in from the left? (Use + to the right and - to the left to distinguish direction in your answer.) Answer in m/s.arrow_forward

Based on the graphs in the figure below, the initial downward velocity of the fist with mass 0.65 kg is about −13 m/s and the collision time is approximately 25 ms.

Initially, m¡ moves to the right with speed Vo then hits m2 (initially at rest). Calculate the speed of the masses if the collision is inelastic. (Continuation) For elastic collision, let the speed of mass m, and mass m, after collision be v', and v', respectively. Setup the equation for conservation of linear momentum and setup the equation for conser- vation of energy. Solution: From conservation of momentum, we have m¡Vo = m¡v + m,U,. For conservation of kinetic energy, we have + = m-m, 2.c (Continuation) Show that the speed of m, after collision is given by v, Vo. Then show that the mi+m2 2m speed of mass m2 after the elastic collision is given by v, -Vo. Hint: Solve the two unknowns v', m1+m2 %3D and v, from the result of item 5.arrow_forwardConsider the before- and after-collision momentum vectors in the diagram below.

The angle between the ball's initial velocity vector and the wall is θi as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is Δt , and this collision is completely elastic. Friction is negligible, so the ball does not start spinning.
