Shot put: Since the shot -

Since the shot - put is a solid sphere made of metal and its mass is equal to the product of its volume and density, we need to find the volume of the sphere. Initial KE of the shotput = 1 2(10 kg)(1 m/s2)= 5 J Initial P E of the shotput at a height 1.5 m above ground = mgh = (10 kg)(10 m/s2)(1.5 m) =150 J Total initial energy of the shotput =155 J Since air resistance is negligible and final potential of the shotput as it hits the ground (h =0) is zero, kinetic energy of the shotput on hitting the ground = 155 J. 铅球的英语是shot。 shot put ; putting the shot 推铅球 shot的例句 1、A popular traditional sport is the digor, a type of shot put . 一种很普遍的传统运动是digor，是推铅球的一种类型。 2、They tied for the third place in the shot put . 他们在推铅球项目中并列第三。 3、Development and Application of an Electronic Measure Instrument for Shot-putting Result. 铅球成绩电子测量仪的研制及应用 4、An analysis of juvenile athletes' standing ...
