From what might be a possible scene in the comic book The X-Men, the Juggernaut (mJ) is charging into Colossus (mC) and the two collide. The initial speed of the Juggernaut is vJi and the initial speed of Colossus is vCi. After the collision, the final speed of the Juggernaut is vJf and the final speed of Colossus is vCf as they each bounce off of the other, heading in opposite directions. a. What is the impulse experienced by the Juggernaut? b. What is the impulse experienced by Colossus? c. In your own words, explain how these impulses must compare with each other and how they are related to the average force each superhero experiences during the collision.
To lift off from the Moon, a 9.50 105 kg rocket needs a thrust larger than the force of gravity. If the exhaust velocity is 4.25 103 m/s, at what rate does the exhaust need to be expelled to provide sufficient thrust? The acceleration due to gravity on the Moon is 1.62 m/s2.
A particle of mass m moving along the x-axis with a velocity component +u collides head-on and sticks to a particle of mass m/3 moving along the x-axis with the velocity component −u. What is the mass M of the resulting particle?
A space station contains 11 modules each with a mass of 13 000 kg, moves at a speed of 4.0km/s. It is equipped with an emergency collision avoidance system whereby an explosive chargecan be detonated to release one of the modules. The collision alarm sounds, and thecommander detonates a charge, releasing one of the modules at a speed of 1400 km/hwith respect to the station, directed opposite to the original direction of travel of the station.Find the resulting change in the speed of the station.
A 0.8 kg block of wood is sliding across a floor at 2 m/s when a half-gram nail from a nail gun travelling 67 m/s horizontally at an angle 35° relative to the direction of the block embeds itself into the wood. (So, the 35° angle is with respect to the x-axis, with x and y both being in the horizontal plane.) (a) What would be the velocity of the block/nail system just after impact? Find also the magnitude and direction of the velocity. Assume that the impact is so fast that friction between the block and the floor can be ignored. (b) How much energy was lost during this collision?

Space probes may be separated from their launchers by exploding bolts. (They bolt away from one another.) Suppose a 5600 kg satellite uses this method to separate from the 1800 kg remains of its launcher, and that 7000 J of kinetic energy is supplied to the two parts. What are their subsequent velocities (in m/s) using the frame of reference in which they were at rest before separation? (Assume the final velocity of the satellite is in the positive direction. Indicate the direction with the sign of your answer.) Vsatellite m/s Viauncher m/s
