Sagot :
Kinetic energy in joules is lost during the collision is 0.3888J
Mass of ball= 0.240kg,
Initial velocity = v1 = 3m/s
velocity after collision = v2 = 2.4m/s
Duration of contact of the billiard ball will the bumper: t=0.0150s
Energy lost during collision = E loss= E1 - E2
E loss = 1/2 * m * ([tex]v1^{2}[/tex] - [tex]v2^{2}[/tex]) = 1/2 * 0.24* (9 - 5.76) = 0.3888J
Examples of kinetic energy being converted into and out of different forms of energy may help people to understand it better. To accelerate a bicycle to a desired pace, for instance, a biker uses the chemical energy from meals. Unless there is additional effort required to overcome friction and air resistance, this speed can be maintained on a flat surface. The process of turning the chemical energy into kinetic energy, the energy of motion, is not entirely efficient and results in heat buildup inside the cyclist. The bicycle's and the cyclist's kinetic energy can be transformed into many types of energy. For instance, the cyclist might come across a slope that is just tall enough to coast up, causing the bicycle to come to an abrupt stop at the top. Kinetic energy in joules is lost during the collision is 0.3888J
