同5月3号sat2 physics...可惜我也看不懂题.
外国人。。。你可以翻译下吗
好吧,我大概懂意思了,我是初中的无能解决
不过你可以用动能定理求的吧。。。
当 一个小孩在一个有微风的日子里放风筝,一阵大风引起了风筝以直径1.6米每秒的圆心轨迹在空中飞行 如果这个风筝是做圆周运动那么将转变为下降的力
问风筝在大风的影响下多快会降落(俯冲)至地面?
a. 3.14m/s b. 5m/s c. 38m/s d. 9.8m/s e. 15.7m/s
公式忘记了 翻译在此 答案应该会很快就能自己做出来的吧 就用一个公式而已 目测是先算半...

公式忘记了 翻译在此 答案应该会很快就能自己做出来的吧 就用一个公式而已 目测是先算半径然后再用公式算出直线速度。加油!
