A futuristic design for a car is to have a large solid disk-shaped flywheel within the car storing kinetic energy. The uniform flywheel has mass 370 kg with a radius of 0.500 m and can rotate up to 320 rev/s. Assuming all of this stored kinetic energy could be transferred to the linear velocity of the 3500-kg car, find the maximum attainable speed of the car.
Answer : , and
Explanation :
Given that,
Charge of the object q =
Electric field in x-direction
Electric field in y- direction
Electric field in z - direction
Now, using formula
Now, the force on the object in x- direction
The force on the object in y- direction
The force on the object in z- direction
Hence, this is the required solution.
B. Elastic potential to kinetic energy
The elastic potential energy in the slingshot will be transferred to the stone as kinetic energy as the stone is launched.
I think it is D but im not sure
