For this problem, take right as the positive direction and left as the negative direction. Bouncy ball a of mass ma =2 kg is moving to the right at 2 m/s when it collides with and bounces off a second ball of mass mb = 3 kg moving to the left at 3 m/s. After the collision, the ball b is moving to the right at 1 m/s. What is the final velocity of ball a? Be careful to enter the correct +/- sign, and round your answer to one decimal place. 0.5 m/s O -0.5 m/s O -12.5 m/s O -4.0 m/s 4.0 m/s 12.5 m/s

T3.29 Please help me answer this physics question.

On a frictionless air track, a 0.175 kgkg glider moving at 1.20 m/sm/s to the right collides with and sticks to a stationary 0.275 kgkg glider.   1.What is the net momentum of this two-glider system before the collision? Use coordinates where +xx is in the direction of the initial motion of the lighter glider. 2.What must be the net momentum of this system after the collision? 3.Use your answers in Parts A and B to find the speed of the gliders after the collision. Is kinetic energy conserved during the collision?

A ball of mass 0.305 kg that is moving with a speed of 5.8 m/s collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.2 m/s. ▼ Part A Calculate the velocity of the target ball after the collision. Express your answer to two significant figures and include the appropriate units. = μᾶ Part B Value Units Submit Request Answer ? Calculate the mass of the target ball. Express your answer to two significant figures and include the appropriate units.

A 35.0 g bullet strikes a 5.0 kg stationary wooden block and embeds itself in the block. The bullet and block fly off together at 8.6 m/s. What was the original velocity of the bullet? A 1.24 m/s B 9.83 m/s 144 m/s D 1240 m/s O O O O

Answer part a, b and c

A hockey puck with a mass of 0.170 kg moving in a straight line at 1.7 m / s collides with an identical puck that is at rest. As a result, the first disk deviates an angle of 30 ° from its original path and continues to move with a speed of 0.45 m / s. What is the angle of the final velocity of the second disk?

A two dimensional collision between a green and a purple ball, where the purple ball strikes the green. If the data for both objects' velocities (x and y components) versus time are provided, and the mass of the balls are identical, what is a way to determine if the momentum of the system conserved? Explain your methodology. Green ball: vx = 0 m/s from t = 0 s to t = 0.4 s vx = 17.42 m/s from t = 0.5 s to t = 5 s vy = 0 m/s from t = 0 s to t = 0.4 s vy = -8.01 m/s from t = 0.5 s to t = 5 s   Purple ball: vx = 22.3 m/s from t = 0 s to t = 0.4 s vx = 4.878 m/s from t = 0.5 s to t = 5 s vy = 2.6 m/s from t = 0 s to t = 0.4 s vy = 10.61 m/s from t = 0.5 s to t = 5 s
