单班普物的考古题，不知道他面对不同授课对象题目会不会差很多

但我还是先转了

P.S. 因为找考古题的时候发现王名儒的普物没有收到精华区，所以才转的

其他如果有收到精华区的就自己找吧

标题: [试题] 101上 王名儒 普通物理学甲上 期中考

时间: Thu Oct 24 23:37:36 2013

课程名称︰普通物理学甲上

课程性质︰必修

课程教师︰王名儒

开课学院：工学院

开课系所︰材料系

考试日期（年月日）︰101.11.8

考试时限（分钟）：120 分钟

是否需发放奖励金：是

（如未明确表示，则不予发放）

试题 :

1. A ball is thrown horizontally from the top of a 20-m high hill. It strikes

the ground at an angle of 45度. With what speed was it thrown ?

2. A block is suspended by a rope from the ceiling of a car. When the car

rounds a 50-m radius horizontal curve at 20 m/s, what angle does the rod make

with the vertical ?

3. Find the change of the kinetic energy of a particle moving under the force

F(x,y) = x^2y i + xy^2 j along the curve y = x^2 from point (0,0) to (2,4).

SI units are assumed.

4. Describe properties of the frictional force (for both static and kinetic).

Draw a simple graph to show the relationship between the magnitude of the

frictional force and the applied external force.

5. A uniform string having mass m is fixed on a frictionless table with half

its total length, L/2. The other half is hung vertically outside this table.

If this string is released freely at one moment, how long will it take for

this string being fully out of the table ?

6. A 30 kg steel block is dropped from a height of 20 cm above a thin thin

rod made of aluminum. The Young's modulus of aluminum is 70*10^9 N/m^2, the

cross-sectional area of this rod is 1.0 cm^2 and the rod length is 10 cm.

Find the maximum distance which the rod is compressed assuming the ground

and the block are perfectly rigid.

7. A playground merry-go-round has a radius of 3.0 m and a rotational inertia

of 600 kg m^2. It is initially spinning at 0.8 rad/s when a 20 kg child

crawls from the center to the rim. When the child reaches the rim, the angular

velocity of the merry-go-round becomes ?

8. Find the rotational energy of a disk with radius R and mass m rolling from

the rest on a 45度 ramp for a distance L.

9. Find the gravitational force experienced by a particle (mass m) at a

distance r from the center of a uniform spherical star with mass M and

radius R.

10. A large tank with height H is filled with water. There are two small hole

in the bottom, one with radius r and the other 2r. Find the speeds of water

leaving the small hole and the large hole.
