a werewoflf vaulting over a fence is spotted by some hunters. The hunters shoot a specially molded silver bullet and hit the creature in the shouldr. With a diplay of incredible stenght the werewolf hold on to the bar and beings to rotate similar to a gymnast. Asume grictinless rotation. Mass of the Bullet=0.05kg, Initial Velocity of Bulllet =100m/s, Moment of interi fof werwolf =23.33 kg*m^2, r= 1.0m (distance from axis of raotation to bullet strike.
a) find the angular velocity of the werewolf after the collison
b is kinetic energy conserved when comparing teh system before and after the collision?
c) if the bullet comes to rest in the werewolf in 0.05 seonds what torque does the werewolf experience?
An airplane has a mass of 2.6 x10^6 kg, and the air flows past the lower surface of the wings at 95m/s. If the wings have a surface area of 1200m2, how fast should the air flow over the upper surface of the wing if the plane is to stay in the air?..

ball rolls horizontally off the edge of a tabletop that is 1.80 m high. It strikes the floor at a point 1.32 m horizontally away from the table edge. (Neglect air resistance.) (a) How long was the ball in the air? s (b) What was its speed at the i..
A 151 kg car rounds a curve of radius 163 m at 46 m/s. The acceleration of gravity is 9.8 m/s2 . What force must the road exert on its tires to hold the car on course? find out its speed when it has moved?
A child in danger of drowning in a river is being carried downstream by a current that has a speed of 2.75 km/hr. The child is 0.560 km from shore and 0.750 km upstream of a boat landing when a rescue boat sets out. If the boat proceeds at its maximu..
Assuming that air resistance is simply a constant 95 N force on the person during the fall, evalute the person’s velocity just before hitting the net.
A string trimmer is a tool for cutting grass and weeds; it utilizes a length of nylon "string" that rotates about an axis perpendicular to one end of the string. What is the length of the rotating string
With what velocity does the wrench strike the ground. What is magnitude and direction of the boat's acceleration? Enter a positive answer for a direction due west, or a negative answer for a direction due east.
when it falls back it hits the ground with speed v1=50m/s. The mass of the ball is m=20g. Illustrate what is the total work done by the drag force while the ball is in the air?
