Answer:
Explanation:
Given
Radius of bicycle wheel
Initial angular velocity
It rotates 3 revolution in 5 s therefore
using
where
Total acceleration of any point will be a vector sum of tangential acceleration and centripetal acceleration
Tangential acceleration
Answer:
Use the method on the image and solve it.
Explanation:
In the parallel combination, the equivalent resistance is given by :
4. When three 150 ohms resistors are connected in parallel, the equivalent is given by :
5. Three resistors of 20 ohms, 40 ohms and 100 ohms are connected in parallel, So,
Hence, this is the required solution.
Answer:
51.94 ft/s²
257.63 ft/s
Explanation:
t = Time taken = 4 s
u = Initial velocity = 34 mi/h
v = Final velocity
s = Displacement = 615 ft
a = Acceleration
Converting velocity to ft/s
Equation of motion
Acceleration is 51.94 ft/s²
Final velocity at this time is 257.63 ft/s
