物理基礎です。 (3)の問題ですが、❓になっているところがどう計算すればこうなるのか理解できません... よろしくお願いいたします。

物理基礎 テキスト 第1講 |2 地面からの高さがh [m]の地点から,鉛直上向きに初速度 vo[m/s]でボールを投げた。 ボールは最高点で一度停止してから落下し,投げ上げた地点を通過して地面に達した。重力 加速度の大きさはg [m/s] とする。 (1) ボールが最高点に達する時間は,投げ上げてから何秒後か。 (2)ボールの最高点の高さは,投げ上げた地点から何mの高さか。 (3) ボールが投げ上げた地点を通過するのは,投げ上げてから何秒後か。 (4) ボールが地面に達するのは,投げ上げてから何秒後か。 (5) ボールが地面に達する直前の速さはいくらか。

b. [1+] Let t(n) be the number of total partitions of n, as defined in Exam- ple 5.2.5. Let g(n) have the same meaning as in Exercise 5.26. Deduce from (a) that g(n) = 2"t(n) for n >1. c. [2+] Give a simple combinatorial proof of (b). 5,37. a. [2+] Let 1=D po(x), pi(x), be a sequence of polynomials (with coeffi- cients in some field K of characteristic O0), with deg pn=n for all nE N. Show that the following four conditions are equivalent: ) Pn(x + y) =DE>o (") Pe(x)pnーk(y), for all n eN. (i) There exists a power series f(u)=aju+azu'+ E K [[u]] such that と P(x)- un expxf(u). (5.110) n! n>0 仮定 NOTE: The hypothesis that deg pPn=nimplies that aj ¥ 0. () E20 Pa(x) = (E>0 Pn(1)). (iv) There exists a linear operator Q on the vector space K[x] of all poly- nomials in x, with the following properties: ●Ox is a nonzero constant ●Qis a shift-invariant operator, i.e., for all aeK,Qcommutes with the shift operator E4 defined by E® p(x)=D p(x +a). ● We have Qpn(x) =D npn-1(x) for all n e P. NOTE: A sequence po, Pi, .. . of polynomials satisfying the above con- ditions is said to be of binomial tvpe. The operator Q is called a delta
