Subject: Complaint

Dear Mr. Price,

I have eaten in your restaurant many times and have always been happy with the food and service. This makes what happened last Saturday even more disappointing(失望).

It was my son’s birthday so we booked a non-smoking table at your restaurant for 7:30 p.m. We arrived on time but were told that our table was not yet ready. At 8:00 p.m., we were given a table in the smoking area. I asked to move but I was told that there were no other tables. A lot of people were smoking so it was uncomfortable and unhealthy.

Our first waitress, Janet, was very polite and helpful. She gave us free drinks for waiting so long. Our food also came quickly and looked fresh and tasty. When my wife had eaten most of her meal, she found a dead cockroach(蟑螂)in her vegetables. She was shocked and wanted to leave. At first, the waitress told us it was a piece of garlic(作料).When we told her it had legs, she apologized

(="said" sorry) and took the food away.

We asked for the pay for my wife’s meal bill, expecting not to pay for my wife’s meal. Nobody came. After 15 minutes, I asked to see the manager. The headwaiter told us that you were on holiday. I complained again about the horrible cockroach. He told me Janet had finished work. He didn’t believe my story and gave me a bill for three meals. I argued with him but was forced(被迫)to pay.

The waitress, Janet, was always friendly, but I would like an apology from your impolite headwaiter and a full refund(退款)for our meal. It cost $68. Until then, I will not be eating at your restaurant or recommending it to anyone.

You can contact me at 742-3254 or through e-mail if you want more information.

Thank you for your attention.

Yours sincerely,

Raymond Yuen

（13分）某同学利用下述装置对轻弹簧的弹性势能进行探究：一轻质弹簧放置在光滑水平桌面上，弹簧左端固定，右端与一小球接触而不固连；弹簧处于原长时，小球恰好在桌边缘，如图（a）所示，向左推小球，使弹簧压缩一段距离后由静止释放，小球离开桌面后落到水平地面，通过测量和计算，可得弹簧压缩后的弹性势能。回答下列问题：

（1）本实验中可以认为，弹簧被压缩后的弹性势能与小球抛出时的动能相等。已知重力加速度大小为.为求得，至少需要测量下列物理量中的（    ）（填正确答案的番号）

A．小球的质量

B．小球抛出点到落地点的水平距离

C．桌面到地面的高度

D．弹簧的压缩量E．弹簧原长

（2）用所选取的测量量和已知量表示，得=____________.

（3）图（b）中的直线是实验测得的图线，从理论上可推出，如果不变，增加，图线的斜率会________（填“增大”、“减小”或“不变”）；如果不变，增加，s—图线的斜率会________（填“增大”、“减小”或“不变”）。由图（b）中给出的直线关系和的表达式可知，与的________次方成正比。
