1: Calculate angular acceleration using that torque formular: torque(t) = inertia(I)* Angular Acceleration(a). then w=at get w.

2: then use v=wr calculate velocity (r is the distance from CM to B)

3. then do distance d= vt

• How can you calculate t? In addition, there is no pivot -Leileima- ♀ 给 Leileima 发送悄悄话 Leileima 的博客首页 (99 bytes) () 12/14/2024 postreply 09:22:19

• you want Torque(t)? I thought you want Time (t).. -zeno- ♀ 给 zeno 发送悄悄话 (81 bytes) () 12/14/2024 postreply 10:31:24
