A 20 kg truck drives in a circle of radius 4 m at 10m/s. What is the
centripetal force on the truck?
A. 500 N
B. 650 N
C. 350 N
D. 800 N



Sagot :

  • Mass=m=20kg
  • Radius=r=4m
  • Velocity=10m/s=v

We know

[tex]\boxed{\sf F_c=\dfrac{mv^2}{r}}[/tex]

[tex]\\ \sf\longmapsto F_c=\dfrac{20(10)^2}{4}[/tex]

[tex]\\ \sf\longmapsto F_c=\dfrac{20(100)}{4}[/tex]

[tex]\\ \sf\longmapsto F_c=\dfrac{2000}{4}[/tex]

[tex]\\ \sf\longmapsto F_c=500N[/tex]
