A20.0 kg body is moving through space in the positive direction of an x axis with a speed of 200 m/s when, due to an internal explosion, it breaks into three parts. one part, with a mass of 10.0 kg, moves away from the point of explosion with a speed of 100 m/s in the positive y direction. a second part, with a mass of 4.00 kg, moves in the negative x direction with a speed of 500 m/s. (a) in unit-vector notation, what is the velocity of the third part? (b) how much energy is released in the explosion? ignore effects due to the gravitational force.

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
