You kick a soccer ball with a mass of 2.5 kg at a speed of 10 m/s towards the net. The soccer ball has a kinetic energy of
(Don't forget your units!)

answer

125 J

explanation

formula for kinetic energy is K = mv^2/2

plug in 2.5 kg for m and 10 m/2 for v

K = 2.5*10^2/2

K = 2.5 * 100 / 2

K = 250 / 2

K = 125 J

oil flow is a highly convective flow compared to water flow at normal temperature and pressure.

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.
