WebThe speed of the ball just before reaching the floor is 8.0 m s. . The ball leaves the floor with an angle of 65 ∘ to the floor as shown. (a). Due to the collision with the floor, the ball losses 30 % of its initial kinetic energy. Show that the leaving speed of the ball from the floor is around 7 m s − 1 . [ 2] (b).

WebJan 14, 2024 · Inelastic compression means there is internal friction which increases the temperature of the ball material, resulting in heat transfer to the cooler environment. This loss of energy is at the expense of the macroscopic kinetic energy that the ball had at … WebDec 31, 2024 · The compression of an elastic ball is proportional to the applied force. At the moment of the collision the portion of the ball in contact with the object is forced to move immediately with its velocity, while the rest of it is accelerated by the force of compression. boat music airbud

WebA player bounces a basketball on the floor, compressing it to 80.0% of its original volume. The air (assume it is essentially N2 gas) inside the ball is originally at 20.0°C and 2.00 atm. The ball’s inside diameter is 23.9 cm. (a) What temperature does the air in the ball reach at its maximum compression? Assume the compression is adiabatic and treat the gas as … WebBall compression is a measure of a ball’s hardness. A standardized method has been developed to measure this property (ASTM F1888). The test apparatus is depicted in Fig. 3.1. The test involves measuring the … WebThe push that the ball receives from the floor at the moment of the impact causes it to bounce upwards. The moving ball gains kinetic energy when it bounces, and loses … boat mufflers exhaust
