a 10 kg ball is thrown up with a speed of 19.9m/s. calculate the work done by its rate in 1 sec

Answer:
Given in the question you then massive block myself block That it is represented by M. which is given one Kg. Gravitational ecoterrorism gravity is no. Exelon is um C is equal to 9.8 m/s square. And speed or block V is equal to 19.9 m/s. Let height race In 1 2nd. We catch let at least in one second be it. So we can date it is equal to ut minus a half G. T square against substituting the value in this. So we can write that is equal to Value of initial velocity. That is given 19.9 And time is given 1 2nd -1 x two into 9.8 into one. So after care person we will get at is equal to 15 m. Hence work done by weight is what you've done. David W is equal to MG into edge here. Mgs were clear downward and displacement is in a poor direction. So Here angle only cost 180. Now after you're doing after securing the value we will get one into Massive block that is one Kg. Gravitational expression that is given 9.8. And to hide we have 15 and value of course vanity that is -1. Now going to further calculation So after it'll present we will get 147 do is required work can be we're done being 100 -147 Jule. That was the expert answer to this question. Thank you
