Answer:
The torque must be supplied by the motor to keep the wheel rotating at a constant angular velocity is 12 N-m.
Explanation:
Given that,
The coefficient of kinetic friction with the wheel is 0.60
Force acting against the wheel, F = 40 N
Let the distance is, r = 0.5 m
Torque is given by the product of force and distance. Here, the force will be :
Torque is given by :
So, the torque must be supplied by the motor to keep the wheel rotating at a constant angular velocity is 12 N-m.
Answer:
the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is 360 m/s
Explanation:
The computation of the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is as follows:
The ball momentum is
As there is a similar momentum
So,
Hence, the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is 360 m/s
