In a certain men's track and field event, the shotput has a mass of 7.30 $\mathrm{kg}$ and is released with a speed of 15.0 $\mathrm{m} / \mathrm{s}$ at $40.0^{\circ}$ above the horizontal over a man's straight left leg. What are the initial horizontal and vertical components of the momentum of this shotput?

$83.9 \mathrm{kg} \cdot \mathrm{m} / \mathrm{s}$ ; $70.4 \mathrm{kg} \cdot \mathrm{m} / \mathrm{s}$

in discussion. We have given moss, whoa softwood, that is I am equal to 7.3 energy. Also the speed of short for that is the equal to 15 m/s and angle good I mean thought was and origin that is Changed up equals to 40 digging. Now comes to are mm So here we had a blink flying go. The momentum of a short word for horizontal component. So we know that initial moment down of a short board can be expressed as a P. I. Equal to M marty club I V. No. Yeah. And is the mass of the sort. We is the spirit of the sort. And pia is actually the initial momentum of the shop. So we substitute 7.3 Kz for M and 15 m per second. Four we therefore we get P I equal to 7.3 Many people are by 15. So we get the I equals two 109 why kilogram meter. Part second. No, the or a gentle component of the initial momentum of a short book can be expressed as B of X. Equal to be I My people are by course cheap now. Here we substitute 109.5 kilometer per second for P I. And 14 2040. To therefore we get P of X equality. 109.5 million people have I almost 40 degree. So from about we get P of X equal to 83. 1 89. Hello Graham later. But six. And the horizontal component of the initial momentum of a short book. It was 83.89 kg meter, but second now similarly comes to part the Here we are going to calculate a vertical component of the initial momentum of a short. It's going to be expressed as P of Y equal to E I sign Cheetah. Now, here we substitute. 109.5 kilogram meter per second for P and 1484 Tita. They're falling at P or five equals 2 109.5 multiple. Have I signed 40 digging. So from above we get p of y equals two 75. So mine kilogram meter sex and the vertical component of the nation, momentum of a short book equals to 70.39 kg meter per second. Or you can say 70.4 kg meter per second approximately.
