2019bpho竞赛真题资料分享 提前体验牛剑笔试难度

bpho竞赛的题目和和牛剑笔试面试题相似度很高，不管是和牛津的PAT还是和剑桥的自然科学笔试比，都有很像的地方，所以如果你也想有想冲牛剑的想法，不妨尝试去做做BPHO的题，万一练好了既能参加竞赛做背提，又能提前为年底的面试做练习，何乐而不为呢？

2019年bpho竞赛真题精选

h)  This question concerns three vessels at sea: a ferry (F), a container ship (C), and a pilot

boat (P). The ferry is sailing on a bearing of 090◦ at 5 m s−1. Relative to the ferry, the

container ship is sailing on a bearing of 160◦. The pilot boat is sailing on a bearing of

270◦ at 7.5 m s−1, and the pilot boat observes the container ship moving on a bearing of120◦ .

Determine the speed and direction of the container ship relative to the water. Note: all bearings are measured clockwise from North.

i)  A car accelerates from a standing start. If the mass of the car is m, and the car is driven at constant driving power P , find an expression for the velocity of the car v as a function of distance travelled from a standing start, x. Ignore resistive effects and inefficiencies in power transmission.

j)  An experiment is proposed which involves submerging a ball of mass m and radius r to a depth of d ≫ r in a swimming pool. The ball is then released, and emerges from the water and rises to a height h ≫ r above the surface. The quantities d and h are measured from the centre of the ball to the water surface. An initial model is proposed, which ignores any resistive effects and the inertia of the water. Determine the prediction this initial model makes for the ratio h/d in terms of m, r and the density of water, ρ.

不知道大家觉得上面这3道题好不好完成呢？BPhO竞赛非常注重思维逻辑的展现，所以每道题都要写出证明过程。只写答案是不得分的，相反如果写出部分正确思路，哪怕答案没对也是可能有分的。如果大家不知道怎么根据BPHO这样的特点去做相应的联系，欢迎点击这里预约试听【橡沐BPHO课程班】——
