A missile is being shot with an initial velocity of 60m/s at an angle of 60 degrees with respect to the horizontal. Located at a distance of 1000 meters from the missile launch, you are located at a height of 150 meters and try to intercept the missi..
A bicycle wheel is spinning with an angular velocity of 20 rad/s. How long does it take the wheel to come to rest
An electrical motor can accelerate a ferris wheel whose moment of inertia is 20,000 kg-m^2 from rest to 10 rev/min in 12 sec. When the motor is turned off, the ferris wheel slows down from 10 to 8 rev/min in 10 sec due to frictional losses.
