Then the speed of the rider is, v = 2m/s
The linear velocity of an object in a straight line is its speed.
The following is the relationship between linear and angular velocity:
v = rω
The circumference of the bicycle wheel is,
2
r = 2
r = 0.318m
The angular velocity of the wheel is,
ω = 1rev/sec = 2
rad/s
Then the speed of the rider is,
v = rω
v = 0.318×2π
v = 2m/s

The Answer is D
Because you add all of them to equal 9 atoms
Answer:
formula used K=F/∆l
∆l is the elongation of the spring
- F=10N
- ∆l=20mm===> 0.02m
- K=10N divided 0.02m= 500N/m
