Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are v1i = +34.3 cm/s and v2i = −20.1 cm/s, what are the velocities of the balls after the collision? Assume friction and rotation are unimportant. (Indicate the direction with the sign of your answer.) v1f = cm/s v2f = cm/s
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.)
Two hockey pucks slide along a flat sheet of ice with no friction, and then collide with each other. The diagram below shows a top-down view of the colliding hockey pucks. The masses of the hockey pucks are mA = 2.00 kilograms (kg) and mB = 1.50 kg.
