單班普物的考古題，不知道他面對不同授課對象題目會不會差很多 但我還是先轉了 P.S. 因為找考古題的時候發現王名儒的普物沒有收到，所以才轉的 其他如果有收到的就自己找吧 ※ [本文轉錄自 NTU-Exam 看板 #1IQJx2Oz ] 作者: Standpoint (旋風企鵝) 看板: NTU-Exam 標題: [試題] 101上 王名儒 普通物理學甲上 期中考 時間: Thu Oct 24 23:37:36 2013 課程名稱︰普通物理學甲上 課程性質︰必修 課程教師︰王名儒 開課學院：工學院 開課系所︰材料系 考試日期（年月日）︰101.11.8 考試時限（分鐘）：120 分鐘 是否需發放獎勵金：是 （如未明確表示，則不予發放） 試題 : 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. --
