Apendulum consist of three identical concentrated masses mc=md=me=2kg positioned as shown on a light but rigid bar. the pendulum is swinging through the vertical positon with a counter clockwise angular velocity =9rad/s when two bullets having the same mass of .06 kg are fired with their prespective direction shown with the different velocities a 400m/s bulllet a strickes the middle mass d and 300 m/s bullet b strickes the lower mass e simultaniously bullent a embedded with mass d and bullet b embedded with the mass e after impact calculate the angular velocity which the pendulum has immidiately afterimpact

The particles of the gas inside the ball heats up, bouncing off each other and spreading farther apart.hope my answer has you : )

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
