Two ice pucks (one orange and one blue) of equal mass are involved in a perfectly elastic glancing collision as shown in the figure below. The orange puck is initially moving to the right at v strikes the initially stationary blue puck, and moves off in a direction that makes an angle of e = 34.0° with the horizontal axis while the blue puck makes an angle of o = 56.0° with this axis as in figure (b). Note that for an elastic collision of two equal masses, the separation anglee + o = 90.0°. Determine the speed of each puck after the collision. = 3.40 m/s, m/s Vof Vbf m/s Voi Before collision After collision

Under many conditions, the center of mass of a system of particles can represent the system as a whole. But how far does this rule extend? Consider two identical particles traveling toward each other at the same speed. By examining this system, choose the correct response. 1)The momentum and kinetic energy of the center of mass is equivalent to that of the system of particles. 2)The kinetic energy, but not the momentum, of the center of mass is equivalent to that of the system of particles. 3)Neither the momentum nor the kinetic energy of the center of mass is equivalent to that of the system of particles. 4)The momentum, but not the kinetic energy, of the center of mass, is equivalent to that of the system of particles.

Two blocks are released from rest on either side of a frictionless half-pipe (see the Figure below). Block B is less massive than block A. The height HB from which block B is released is less than HA, the height from which block A is released. The blocks collide elastically on the flat section. HA B HB 1) After the collision, which is correct? Block A rises to a height greater than HA and block B rises to a height less than HB. Block A rises to a height less than HA and block B rises to a height greater than HB. Block A rises to height HA and block B rises to height HB. Block A rises to height HB and block B rises to height HA. The heights to which the blocks rise depends on where along the flat section they collide. Submit

Two blocks of masses m, = 2.30 kg and m, = 4.60 kg are each released from rest at a height of h = 4.20 m on a frictionless track, as shown in the figure below, and undergo an elastic head-on collision. (Let the positive direction point to the right. Indicate the direction with the sign of your answer.) (a) Determine the velocity of each block just before the collision. V = m/s m/s (b) Determine the velocity of each block immediately after the collision. m/s V2 = m/s (c) Determine the maximum heights to which m, and m, rise after the collision. Yıf = m Y2f = m

A golf ball is moving at speed vo to the East. After deflecting off a tree, it moves at a speed of 0.90vo in a direction which is 25° North of East. Check all the following answers which are true statements. There may be more than one correct answer! The impulse vector (delivered by the tree) has components which point North and West The ball's momentum vector has the same magnitude before and after the collision The impulse vector (delivered by the tree) points purely to the North The ball's momentum vector decreases in magnitude during the collision

Ball having mass 5.5kg and velocity 7.6m/s travels to the east. Impulse given at point O, makes it change direction to north with velocity 4.8 m/s. What is the direction of the given impulse, measured in unit of degrees, if the angle is defined as between the horizontal direction (east) and the impulse?

Two boxes make a perfectly elastic collision on a horizontal frictionless surface as shown in the figure. Box with mass m= 8.0 kg and speed of 4.50 m/s collides with box M. After the collision, box m recoils with a speed of 0.75 m/s. The boxes are in contact for 0.30 s. The magnitude of the average force on the 8.0 kg box, while the two blocks are in contact, is

Two objects collide head-on (see figure below). The first object is moving with an initial speed of  v1i = 7.94 m/s  and the second object is moving with an initial speed of  v2i = 10.00 m/s.  Assuming the collision is elastic,  m1 = 5.17 kg,  and  m2 = 6.29 kg,  determine the final velocity of each object. (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.)

In the figure puck 1 of mass m₁ = 0.50 kg is sent sliding across a frictionless lab bench, to undergo a one-dimensional elastic collision with stationary puck 2. Puck 2 then slides off the bench and lands a distance d from the base of the bench. Puck 1 rebounds from the collision and slides off the opposite edge of the bench, landing a distance 5d from the base of the bench. What is the mass of puck 2?
