A billiard ball rolling across a table at 1.50 m/s makes a head-on elastic collision with an identical ball. Find the speed of each ball after the collision when each of the following occurs. (a) The second ball is initially at rest. 1st ball 0 v m/s 2nd ball 1.5 m/s (b) The second ball is moving toward the first at a speed of 1.15 m/s. -1.25 1st Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a ball mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m/s 2nd 1.5 V m/s ball (c) The second ball is moving away from the first at a speed of 0.90 m/s. 0.85 1st Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a ball mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy roundoff error. m/s minimize 2nd 1.5 ball m/s

In an Atwoods Machine lab with m1 = 0.1 and m2 = 0.13 observed acceleration is 1.20 m/s^2. Compare the value with the a(theoretical).   During the momentum collision lab a 2.5kg mass moving with 2m/s hits a stationary 5kg mass. After the collision 2.5kg bounces back with 0.5m/s and 5kg mass moves with 1.2 m/s. Calculate Pi and Pf and compare using percent error. Does this experiment show conservation of momentum?

Question Vị = 8 m/s A Vi = 16 m/s Objects A and B (Mass A = 6kg, Mass B = 4kg) have a head-on collision as shown. Immediately before the collision, Object A has a velocity of 8 m/s to the right, and Object B has a velocity 16 m/s to the left. Immediately after the collision, Object A has a velocity 4 m/s to the left. What is the magnitude and direction of the velocity of Object B ilmmediately after the collision? %3D Answer

Particle 1 has mass m1= 2 kg and velocity v1= 10 m/s . It collides with particle 2 which has mass m2= 20 kg and velocity = -4 m/s. If the velocity of particle 2 after the collision is v2 = - 1.5m/s a. Find the velocity ( ) of particle 1 after the collision. b. Draw a diagram(arrows) representing the masses and velocities before and after the collision.

云 HI 5 F. %24 -10 Part A Jeanette is playing in a 9-ball pool tournament. She will win if she sinks the 9-ball from the final rack, so she needs to line up her shot precisely. Both the cue ball and the 9-ball have mass m, and the cue ball is hit at an initial speed of v. Jeanette carefully hits the cue ball into the 9-ball off center, so that when the balls collide, they move away from each other at the same angle 0 from the direction in which the cue ball was originally traveling (see figure). Furthermore, after the collision, the cue ball moves away at speed vf, while the 9-ball moves at speed vp. (Figure 1) Find the angle 0 that the 9-ball travels away from the horizontal, as shown in the figure. Express your answer in degrees to three significant figures. > View Available Hint(s) For the purposes of this problem, assume that the collision is perfectly elastic, neglect friction, and ignore the spinning of the balls.

A mass m1= 3kg slides down slippery ramp, reaching a speed v=9 m/s at the bottom. After reaching the level ground m1 collides with mass m2= 4kg at bottom, sticking together in a perfectly inelastic collision. The combined mass then slides over a floor, finally coming to rest after travelling a horizontal distance x= 6m. a.) What was the height of the ramp, assuming that m1 started from rest? b.) How fast were the combined masses m1 and m2 moving after sticking together?
