A stunt motorcyclist rides with uniform speed on the inside rim of a vertical circular ramp of radius 8m. How fast must the motorcyclist travel to avoid leaving the surface at the top of the loop? 總覺得此題關鍵在uniform speed 我原本是想答案應該是(gR)^(0.5) R是半徑8m,g是重力加速度9.8 但是答案不對 答案是11 m/s 有大大可以幫忙解答嗎? 感謝!!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 120.107.174.101
