An unmanned SpaceX rocket is fired off the launchpad in south Texas on a mission to the International Space Station. The rocket travels straight upwards, reaching a constant velocity of 267 m/s, but it explodes into three equal pieces a few seconds later (Elon is distraught). Immediately after the explosion, controllers at NORAD view the first piece moving to the right at 344 m/s, and the second piece moving straight upwards at 204 m/s. Part A: Draw a picture of the rocket before the explosion and after the explosion. (Hint: your vectors will be momentum vectors!) Part B: Write an equation(s) using the law of conservation of momentum. (Remember: x and y are two different directions!) Part C: What is the speed and direction (angle) of the third piece?

A railroad flatcar is traveling to the right at a speed of 13.0 m/sm/s relative to an observer standing on the ground. Someone is riding a motor scooter on the flatcar. a. What is the magnitude of the velocity of the motor scooter relative to the flatcar if its velocity relative to the observer on the ground is 18.0 m/s to the right? b. What is the magnitude of the velocity of the motor scooter relative to the flatcar if its velocity relative to the observer on the ground is 3.0 m/s to the left? c. What is the magnitude of the velocity of the motor scooter relative to the flatcar if its velocity relative to the observer on the ground is zero? What is the direction of the velocity of the motor scooter relative to the flatcar in this case?
Two soccer players, Mia and Alice, are running as Alice passes the ball to Mia. Mia is running due north with a speed of 6.20 m/sm/s. The velocity of the ball relative to Mia is 4.80 m/sm/s in a direction 30.0∘∘ east of south.
A 1500kg sport car is moving westbound at 20m/s on a level road when it collided with a 4000kg truck driving east on the same road at 15m/s. The two vehicles remain locked together after the collision. a)what are is the magnitude of the velocity of the two vehicles just after the collision?
Your frined drops a tennis ball from her window (66.1 m above the ground). One second later you throw a rock(as a projectile) from the ground. The rock and the ball collide at x=32.6m, y=22 m measured from where the rock was thrown. a.) Determine how many second after the tennis ball is released the collision takes place. b.) Determine the velocity of the tennis ball at the time of the collision with the rock. c.) Determine the initial velocity of the rock in its component form.
3. Harry Potter is doing his usual thing of cruising around looking for the Golden Snitch when a rogue bludger drills him in the arm. We can assume that the bludger is initially moving at a speed of 15.0 m/s and hits Harry directly from the side. If Harry had been moving forward with a speed of 24.0 m/s and the bludger and Harry stick together after the collision, what is their final velocity (both magnitude and direction)? Assume that Harry has a mass of 48.0 kg (including his Nimbus 2000) and that the mass of a bludger is 25.0 kg. m B = 25.0 kg B = 15.0 m/s Bam! Harry+Bludger v = ?

Ernest Goes Fishing. After putting his fishing gear in the canoe he walks back to his car to lock it. Upon returning he finds that the canoe was not secured properly and is now drifting along the pier parallel to it at 1 m/s, without friction. He runs down the pier at 5 m/s and jumps into the canoe that is moving in the same direction he is. When Ernest has landed in the boat, what is its final velocity (in m/s)? Ernest has a mass of 70 kg and the canoe (with fishing gear) has a mass of 30 kg. Use conservation of momentum for an inelastic collision.
The truck in Figure P39.1 is moving at a speed of 10.0 m/s relative to the ground. The person on the truck throws a baseball in the backward direction at a speed of 20.0 m/s relative to the truck. What is the velocity of the baseball as measured by the observer on the ground? Figure P39.1
An experimentalist in a laboratory finds that a particle has a helical path. The position of this particle in the laboratory frame is given by r(t)=Rcost+Rsint+vztk where R, vz, and are constants. A moving frame has velocity (vM)L=vzk relative to the laboratory frame. a. What is the path of the particle in the moving frame? b. What is the velocity of the particle as a function of time relative to the moving frame? c. What is the acceleration of the particle in each frame? d. How should the acceleration in each frame be related? Does your answer to part (c) make sense? Explain.
A girl, moving at 8 m/s on in-line skates, is overtaking a boy moving at 5 m/s as they both skate on a straight path. The boy losses a ball backward toward the girl, giving it speed 12 m/s relative to him. What is the speed of the ball relative to the girl, who catches it?
