Radiation

Radiation can be described as the energy in the form of a particular matter or electromagnetic waves traveling in the air and can be in the form of light, sound, and heat. Radiation can be detected through special instruments like X-rays. The radiation from a cooler object is less intense as compared to the radiation from hot objects.

Q11. As shown in the image below, the freight cars A and Bare approaching each other, and they have a mass of mA = 19 Mg and mB = 14 Mg, respectively. The directions of their initial velocities are shown in the image, and the speeds are vA,1 = 9.2 m/s and vB.1 = 6.8 m/s. If the coefficient of restitution between the bumpers is e = 0.4, determine the velocity of A after collision. Right is considered the positive direction and negative sign must be included if A moves to the left after the collision. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper SI unit. %3D V4,1 A VB,1 В Your Answer: Answer units
