A body is thrown up with a velocity $$100$$ $$ms-1$$. It travels $$5$$ m in the last second of its upward journey. If the same body is thrown up with a velocity $$200$$ $$ms-1$$, how much distance (in$$ $$metre) will it travel in the last second of its upward $$journey(g$$ $$=$$ $$10$$ $$ms-2)$$?

Question

A body is thrown up with a velocity $$100$$ $$ms-1$$. It travels $$5$$ m in the last second of its upward journey. If the same body is thrown up with a velocity $$200$$ $$ms-1$$, how much distance (in$$ $$metre) will it travel in the last second  of its upward $$journey(g$$ $$=$$ $$10$$ $$ms-2)$$?

Infinity Learn · Accepted Answer

$$s=u+a2(2n$$−$$1)$$        $$u=100ms$$−$$1$$,$$a=$$−$$10ms$$−$$2$$ and $$s=5m$$        $$5=100$$−$$5(2n$$−$$1)$$ gives $$n=10sBody$$ when thrown up with velocity $$200$$ $$ms-1$$ will take $$20$$ s to reach the highest point. Distance travelled in $$20th$$ second is $$200$$−$$5(20$$×$$2$$−$$1)=5mIn$$ the last second of upward journey, the bodies will travel same distance.

A body is thrown up with a velocity 100 ms^-1. It travels 5 m in the last second of its upward journey. If the same body is thrown up with a velocity 200 ms^-1, how much distance (in metre) will it travel in the last second of its upward journey(g = 10 ms^-2)?

s=u+a2(2n−1) u=100ms−1,a=−10ms−2 and s=5m 5=100−5(2n−1) gives n=10sBody when thrown up with velocity 200 ms-1 will take 20 s to reach the highest point. Distance travelled in 20th second is 200−5(20×2−1)=5mIn the last second of upward journey, the bodies will travel same distance.
