<>第1关:绘制一个坐标点
1.某轰炸机在h=3km的高空以200m/s的速度水平匀速飞行,到达A点是投下一枚无动力炸弹,不考虑空气阻力,重力加速度g的值取9.8,我们可以通过如下公式得到炸弹在任意时候的位置。
import matplotlib matplotlib.use('Agg') import matplotlib.pyplot as plt
#导入matplotlib.pyplot h, v0, g = 3000, 200, 9.8 for t in [10, 15, 20, 24]: xt =
v0*t yt = h-1/2*g*t**2 plt.ylim((0, 3000)) plt.xlim((0, 5000)) plt.grid('on')
######## begin ############ # 请使用plot函数,绘制一个坐标点 plt.plot(xt, yt, 'ro') ########
end ############## plt.savefig('./student result/%s秒后.png' % str(t)) plt.close()
