Mohon bantuanya para master...... sebuah sepeda beruji 25cm,bergerak dengan laju 2,5 m/s. bila jumlah massa pengendara dan sepeda adalah 50kg berapakah percepatan sentripetalnya ??? dan gaya sentripetal setiap titik m pada roda sepeda itu???

Diketahui : r = 25cm = 2.5 m v = 2.5 m/s m= 50 kg
a) percepatan sentripetral => as = V² / r as = 2.5 ² / 2.5 as = 6.25 / 2.5 as = 2.5 m/s²
b) Gaya Sentripetral => Fs = m x v² / r Fs = 50 x 2.5² / 2.5 Fs = 50 x 6.25 / 2.5 Fs = 50 x 2.5 Fs = 125 N
r = 25cm = 2.5 m
v = 2.5 m/s
m= 50 kg
a) percepatan sentripetral
=> as = V² / r
as = 2.5 ² / 2.5
as = 6.25 / 2.5
as = 2.5 m/s²
b) Gaya Sentripetral
=> Fs = m x v² / r
Fs = 50 x 2.5² / 2.5
Fs = 50 x 6.25 / 2.5
Fs = 50 x 2.5
Fs = 125 N
menurut hitungan ku hasilnya kaya diatas !
v :2.5m/s
m : 50 kg
a.percepatan sentripetal
=>: as : v²/r
as : 2.5²/2.5
as : 6.25/2.5
as : 2.5m/s²
b. gaya sentripetral
=> fs : m × v²/r
fs : 50×2.5²/2.5
fs : 50×6.25/2.5
fs :50×25
fs :125 N
Hasilnya gue pasti bener dibandingkn lo !z
