WebHow to find kinetic energy without a velocity Problem: The mass of the block is 250kg. The block is pushed with a force of 320N over a distance of 8m. Question:If there was NO friction with the floor, the kinetic energy gained by the block would be [Blank] J, and the speed of the block at 8m would be [Blank]m/s. WebHow is velocity proportional to kinetic energy? Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v 2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. WebBecause the mass m and speed v are given, the kinetic energy can be calculated from its definition as given in the equation KE = 1 2 mv 2. Solution The kinetic energy is given by KE = 1 2 mv 2. 7.13 Entering known values gives KE = 0. 5 ( 30.0 kg) ( 0.500 m/s) 2, 7.14 which yields KE = 3.75 kg ⋅ m 2 /s 2 = 3.75 J. 7.15 Discussion mclassic version 2
