is the collision between the ball and the pendulum elastic or inelastic? Justify your answer by calculating the energy of the kinectic of the system before collision using the value of found vxo found in experiment and the kinectic energy just collision using the experiemental value of h in eq 8.82

6 a) Material point P(m) writes the flat curve, where_r(0+1)²=a influence of central force. Find the power law. a is constant, under the b) At the moment when the particle passes through the position 0, receives an impulse in the direction of its movement, which zeros the radial component of its velocity and doubles the transverse. Prove that the mobile will write the curve 3α I= 2 + cos √√3 2

A pendulum falls from a horizontal position and strikes a stationary mass at its vertical position, with a perfectly elastic collision. Calculate the speed of the stationary mass just after the collision. 0.750m m2 m, = 2.50 kg m, = 8.50 kg

Shows a cube at rest and a small object heading toward it. (a) Describe the directions (angle θ1) at which the small object can emerge after colliding elastically with the cube. How does θ1 depend on b, the so-called impact parameter? Ignore any effects that might be due to rotation after the collision, and assume that the cube is much more massive than the small object. (b) Answer the same questions if the small object instead collides with a massive sphere.

A billiard ball moving at 5.20 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.67 m/s at an angle of 26.0° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. magnitude direction 1.56 × Check the initial and final kinetic energies. You will find that your final kinetic energy is not equal to the initial kinetic energy. m/s ° (with respect to the original line of motion)

A 13 kg body moving at 33 m/s experiences a complete inelastic collision with a 2 kg body moving at 55 m/s. Compute for the final velocity after collision.

A 1.0 kg steel ball and a 2.0 m cord of negligible mass make u simple pendulum that can pivot without friction about the point O, as in Figure 3. This pendulum is released from rest in a horizontal position, and when the ball is at its lowest point it strikes a 1.0 kg block sitting at rest on a shelf. Assume that the collision is perfectly elastic and that the coefficient of kinetic friction between the block and shelf is 0.10.(A) What is the velocity of the block just after impact?(B) How far foes the bock slide before coming to rest (assuming that the shelf is long enough)?

A system consists of two carts that are traveling toward each other so that they will collide. Three different outcomes are shown in the figure below: elastic collision, inelastic collision, and completely (or purely) inelastic collision.     Answer yes or no to the following questions:   For an elastic collision, is total linear momentum conserved?   For an elastic collision, is total kinetic energy conserved?   For an inelastic collision, is total linear momentum conserved?   For an inelastic collision, is total kinetic energy conserved?   For a completely (or purely) inelastic collision, is total linear momentum conserved?   For a completely (or purely) inelastic collision, is total kinetic energy conserved?
