如图所示,一倾角为37°的斜面固定在水平地面上,质量为1千克的物体在平行于斜面向上的恒力F作用下,从斜面的底端A点由静止开始运动,到达B点时立即撤去拉力F。此后,物体到达最高点C。每隔0.2s通过位移传感器测得物体的瞬时速度的大小,下表给出了部分测量数据。(取sin37°=0.6,cos37°=0.8)

试求:

(1)恒力F的大小;

(2)0.6s时物体的瞬时速度;

(3)物体在斜面上运动过程中重力的最大功率;

(4)物体在斜面上运动的过程中,地面对斜面的摩擦力。

A Full-Time School Called Life

You are enrolled in a full-time school called “life”. Each day in this school you will have the opportunity to learn lessons. You may like the lessons or hate them, but you have designed them as part of your curriculum.

Why are you here? What is your purpose? Humans have sought to discover the meaning of life for a very long time. What we and our ancestors overlooked, however, is there is no one answer. The meaning of life is different for every individual.

Each person has his or her own purpose and distinct path, unique and separate from anyone else’s. As you travel your life path, you will be presented with numerous lessons that you will need to learn in order to fulfill that purpose. The lessons you are presented with are specific to you; learning these lessons is a key to discovering and fulfilling the meaning and connection of your own life.

As you travel through your lifetime, you may encounter challenging lessons that others don’t have to face, while others spend years struggling with challenges that you don’t need to deal with. You may never know why you are blessed with a wonderful marriage, while your friends suffer through bitter arguments and painful divorces, just as you cannot be sure why you struggle financially while your peers enjoy abundance. The only thing you can count on for certain is that you specifically need to learn; whether we choose to learn them or not is entirely up to you.

The challenge here, therefore , is to align(与…保持一致)yourself with your own unique path by learning individual lessons. This is one of the most difficult challenges you will be faced with in your lifetime, as sometimes your path will be completely different from others. But, remember, don’t compare your path to the people around you and focus on the difference between their lessons and yours. You need to remember that you will only be faced with lessons that you are capable of learning and are specific to your own growth.

Our sense of fairness is the expectation of equity—the assumption that all things are equal and that justice will always prevail. Life is not, in fact, fair, and you may indeed have a more difficult lift path than others around you, deserved or not. Everyone’s circumstances are unique, and everyone needs to handle his or her own circumstances differently. If you want to move toward calm, you will be required to move out the comparing phrase of “it’s not fair”. Focusing on the unfairness of circumstances keeps you comparing yourself with others rather than appreciating your own special uniqueness. You miss out on learning your individual lessons by distracting yourself with feeling of bitterness and anger.
