Every time the pedals go through a `360^(@)` rotation on a certain bicycle, the tires rotate three times. If the tires are 24 inches in diameter, what is the minimum number of complete rotations of the pedals needed for the bicycle to travel at least 1 mile? (1mile=5,280feet)

The wheels on the old-time bicycle shown in diagram have radii of 60.0 cm and 10.0 cm If the larger wheel is rotating at 12.0 rad s^(-1) What is the angular speed of the smaller wheel ?

solid sphere of mass 5 kg and radius 1 m is rotating about an axis passing through its centre. find constant tangential force required to rotate the sphere with 10 rad/s in two second . also find number of rotations completed by sphere in that time interval.

A student peddles a stationary bicycle. The pedals are connected to a coil of 100 turns and area 0.1 m^(-2) . The coil is placed in a uniform magnetic field of 10^(-2) T , perpendicular to the axis of rotation of the coil. What is the maximum voltage generated in the coil if the coil rotates at 60 revolution per minute?

Some how, an ant is stuck to the rim of a bicycle wheel of diameter 1 m. While the bicycle is on a central stand, the wheel is set into rotation and it attains the frequency of 2 rev/s in 10 seconds, with uniform angular acceleration. Calculate Time taken by it for first complete revolution and the last complete revolution.

Brian plans to complete a 100-mile bike race for charity. According to his registration materials, he will need to ride at an average speed of 12.5 miles per hour if he wants to complete the course before it closes. On a pratice ride the week before the race, Brain rides 60 miles and trackes his speed. For the first 30 miles, his average speed is 16 miles per hour, and for the next 30 miles, his average speed is 15 miles per hour. If Brian can match these speeds for the first 60 miles of the charity race, then he rests for that total of 1 hour after that, what approximately speed must he maintain for the last 40 miles in order to complete the ride on time?

A weightless rigid rod AB of length / connects two equal masses m one particle is fixed at the end B and the other at the middle ofthe rod as shown in the figure-5.131. The rod can rotate in the vertical plane freely around the hinge point/4. Choose the correct option(s) A. The minimum horizontal velocity required to be given to the particle B so as to make the rod go around in the complete vertical circle is sqrt((24 gl)/(5)) B. The minimum horizontal velocity required to be given to the particle B so as to make the rod go around in the complete vertical circle is sqrt((24 gl)/(g)) C. The ratio of compressive force in the rods AC and BC is 2:1 when the masses are at highest point. D. The ratio of compressive force in the rods AC and BC is 3:1 when the masses are at highest point.
