- The figure shows a two-ended "rocket" that is initially stationary on a frictionless floor, with its center at the origin of an x axis. The rocket consists of a central block C (of mass M-6.50 kg) and blocks L and R (each of mass m-1.20 kg) on the left and right sides. Sm explosions can shoot either of the side blocks away from block C and along the x axis. Here is the sequence: (1) At time t-0, block Lis shot to the left with a speed of 3.30 m/s relative to the velocity that the explosion gives the rest of the rocket. (2) Next, at timet -0.6 s, block R is shot to the right with a speed of 3.30 m/s relative to the velocity that block C then has (after the second explosion). At t -3.30 s, what are (a) the velocity of block C (including sign) and (b) the position of its center? (a) Number (b) Number Units UnitsA rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 86.2 × 105 kg, of which 14.7 × 105 kg is fuel. The rocket engine is then fired for 180 s, during which fuel is consumed at the rate of 480 kg/s. The speed of the exhaust products relative to the rocket is 2.98 km/s. (a) What is the rocket's thrust? After the 180 s firing, what are (b) the mass and (c) the speed of the rocket?Two manned satellites approaching one another at a relative speed of 0.300 m/s intend to dock. The first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. If the two satellites collide elastically rather than dock, what is their final relative velocity? Adopt the reference frame in which the second satellite is initially at rest and assume that the positive direction is directed from the second satellite towards the first satellite.

If the two satellites collide elastically rather than dock, what is their final relative velocity in meters per second?

A 65-kg jogger is heading 61° north of east at a speed of 2.7 m/s. Find (a) the magnitude and (b) the direction of the sum of the momenta of the two joggers. Describe the direction as an angle with respect to due east. North EastTwo fun-loving otters are sliding toward each other on a muddy (and hence frictionless) horizontal surface. One of them, of mass 7.50 kg, is sliding to the left at 5.00 m/s while the other, of mass 5.75 kg, is slipping to the right at 6.00 m/s. They hold fast to each other after they collide. (a) Find the magnitude and direction of the velocity of these free-spirited otters right after they collide. (b) How much mechanical energy dissipates during this play?
- A 80.1 kg linebacker (X) is running at 6.71 m/s directly toward the sideline of a football field. He tackles a 91.7 kg running back (O) moving at 9.49 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision, both players momentarily leave the ground and go out‑of‑bounds at an angle ϕ relative to the sideline, as shown in the diagrams. What is the common speed ?f of the players immediately after their impact? What is the angle ϕ of their motion relative to the sideline?A tabletop gamer has designed a game that requires three dice to be thrown onto a tray with a measurement grid. To add an extra degree of randomness, the coordinates of the center of mass of the three dice are used as well. The masses of the three dice are 10.10 g, 15.50 , and 18.70 g, and their respective coordinates after one particular throw are (0.2230 m, −0.1850 m), (-0.3270 m, 0.1830 m), and (-0.3730 m, −0.2550 m). What are the resulting coordinates of the center of mass of the dice, xcm and yem? Xcm = m Ycm = mThe mass of a particular skateboard plus its rider is m, = 76.6 kg, and the skateboarder is holding a book with mass mo = 3.27 kg. Initially atrest, the skateboarder tosses the textbook with a velocity of vb = 4.44 m/s at an angle 0 = 23.3° above the horizontal, and the book is caught by a friend.
