Tốc độ của đĩa là  :
v = 2pi/0,2 =10pi 
Vận tốc dài của đĩa là :
10pi x 0,1 = 3,14 (m/s)
Bài 2:
đổi : 54km/h = 15 m/s
Gia tốc hướng tâm của chất điểm là :
aht = 15*2 / 15 = 15]]> 2021-09-30 01:55:33 UTC https://padlet.com/thanhgianga/12_1176/wish/1779876507 https://padlet.com/thanhgianga/12_1176/wish/1779876543 2021-09-30 01:55:34 UTC https://padlet.com/thanhgianga/12_1176/wish/1779876543 https://padlet.com/thanhgianga/12_1176/wish/1779883852 2021-09-30 01:58:26 UTC https://padlet.com/thanhgianga/12_1176/wish/1779883852 https://padlet.com/thanhgianga/12_1176/wish/1779925174 2021-09-30 02:14:47 UTC https://padlet.com/thanhgianga/12_1176/wish/1779925174
