Two equal-mass balls made of the different materials swing down at end of strings from equal heights and hit identical planks. Ball 1 bounces back , whereas Ball 2 flattens and stops when it hits the plank. Ball 1 knocks the plank over and Ball 2 does not. Use your knowledge on impulse momentum to explain why, specifically the system you choose and include a bar chart of the process that is consistent with your chosen system.

Part A Two identical steel balls, each of mass 2.40 kg, are suspended from strings of length 33.0 cm so that they touch when in their equilibrium position. We pull one of the balls back until its string makes an angle θ = 60.0° with the vertical and let it go. It collides elastically with the other ball. How high will the other ball rise? Part B Suppose that instead of steel balls we use putty balls. They will collide...

Two billiard balls of equal mass move at right angles and meet at the origin of...

Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. Ball A is moving upward along the y axis at vA = 1.9m/s , and ball B is moving to the right along the x axis with speed vB = 5.4m/s . After the collision, assumed elastic, ball B is moving along the positive y axis(Figure 1) . What is the final direction of ball A? What are their two...

Billiard balls A and B of equal mass move at right angles and meet at the origin of an xy coordinate system. Initially ball A moves along the y axis at 2.0m/s and ball B is moving to the right along x axis at 3.7 m/s. After the collision, assumed elastic, ball B moves along the positive y axis with velocity v'B. What is the final direction of ball A and what are the speeds of the two balls?

A swing is made from a rope that will tolerate a maximum tension of 4.95 x 102 N without breaking. Initially, the swing hangs vertically. The swing is then pulled back at an angle of 35.6 ° with respect to the vertical and released from rest. What is the mass of the heaviest person who can ride the swing?

Two metals of equal mass with different heat capacities are subjected to the same amount of...

Two metals of equal mass with different heat capacities are subjected to the same amount of heat. Which undergoes the smaller change in temperature (You must explain/justify your answer)? a) The metal with the higher heat capacity undergoes the smaller change in temperature. b) The metal with the lower heat capacity undergoes the smaller change in temperature. c) Both undergo the same change in temperature. d) You need to know the initial temperatures of the metals. e) You need to...

Consider two urns of balls: the first contains 5 different red balls numbered from 1 to 5 and the second contains 4 different blue balls numbered from 1 to 4. You are asked to pick one ball from the first urn (i.e., the one with red balls) and one ball from the second urn (i.e., the one with blue balls). Each outcome has the form (r, b), where r denotes the number on the red ball and b denotes the...

Two cylinders of identical mass but with different radii roll down a ramp. In your initial post to the discussion, respond to the following: Which cylinder gets to the bottom first? Which cylinder has more total kinetic energy? Why? Now, using the concept of moment of inertia, explain why two objects rolling down an incline (even if they have identical masses) roll at different speeds.

Two blocks with different mass are attached to either end of a light rope that passes...

Two blocks with different mass are attached to either end of a light rope that passes over a light, frictionless pulley that is suspended from the ceiling. The masses are released from rest, and the more massive one starts to descend. After this block has descended a distance 1.20m , its speed is 1.50m/s . a. If the total mass of the two blocks is 16.0kg , what is the mass of the more massive block? Take free fall acceleration...

A machine begins to apply an equal torque to two cylinders of equal mass and equal radius R, so that they begin to rotate about their central axis (the line shown here). One cylinder is solid. The other cylinder is a thin-walled hollow cylinder. After a certain amount of time, what statement can be made about the rotary motion of the cylinders? Question 14 options: a) The cylinders rotate at the same speed. b) This solid cylinder rotates at twice...
