A 1,400 kg stationary object is hit by a 890 kg object traveling at a speed of 0.900c. If the two objects stick together, determine the following. (a) speed of the composite object immediately after the collision (expressed as a multiple of the speed of light) C (b) mass (in kg) of the composite object immediately after the collision kg

please help me with this problem. Given: A ball of clay mass M/8 A larger mass as known as M is attached to a spring with spring constant k. A ball of clay mass "M/8" moves with speed "v" towards a larger mass M. As the a ball of clay hit and sticks on the a larger mass who was initially still. a) What would be the speed of the combination after the collision? b) How much did the spring compressed c) How long did it take for the spring to be compressed due to the collision?

if the velocity of the water is 2 m/s, the equivalent energy/mass of water due to velocity is approximately: A: 1 J/kg B: 2 J/kg C: 10 J/kg D: 20 J/kg

A two-stage rocket (M = 7.50 × 103 kg) initially travels at 4.50 km·s−1 relative to Earth. Explosive charges then separate the capsule (mC = 1.50 × 103 kg) from the booster (mB = 6.00 × 103 kg). After separating, the booster travels at 2.70 km·s−1 along the original direction of motion. a)  What was the speed of the capsule just after the stages separated? b)  How much energy was released by the explosive charges?

A particle of mass m (particle #1) is fired head-on at speed 48 m/s toward another particle of mass 3m (particle #2) which is at rest.  The result of this collision is that #1 comes to a complete stop, and #2 moves forward.  (a) At what speed does particle #2 emerge from the collision?  (b) What fraction of the original kinetic energy is lost during this process?

An object, with mass 88 kg and speed 18 m/s relative to an observer, explodes into two pieces, one 4 times as massive as the other; the explosion takes place in deep space. The less massive piece stops relative to the observer. How much kinetic energy is added to the system during the explosion, as measured in the observer's reference frame?

An object is traveling such that it has a momentum of magnitude 22.2 kg · m/s and a kinetic energy of 242 J. Determine the following. (a) speed of the object in meters per second m/s (b) mass of the object in kilograms kg

Our brave astronaut Ms. Rose Noneck is at rest spacewalking 9.3 m away from her spaceship when her jetpack runs out of electricity (powered by TCC?). And worst – she is down to 60 seconds of oxygen left – there's plenty in her spaceship as well as her delicious lunch of baba ganoush. She remembers Prof. P's class and throws her 23.6 kg jetpack in the opposite direction of her spaceship at 1.4 m/s. Her mass is 55 kg. Will she make it back to her spaceship before she runs out of air? Convince me with numbers - tell me how long in seconds it takes for her to get back. Will we be seeing her in Exam 4? Or is it the end for her?

As shown in the figure below, a bullet is fired at and passes through a piece of target paper suspended by a massless string. The bullet has a mass m, a speed v before the collision with the target, and a speed  (0.516)v  after passing through the target. The collision is inelastic and during the collision, the amount of kinetic energy lost by the bullet and paper is equal to [(0.333)Kb BC] , that is, 0.333 of the kinetic energy of the bullet before the collision. Determine the mass M of the target and the speed V of the target the instant after the collision in terms of the mass m of the bullet and speed v of the bullet before the collision. (Express your answers to at least 3 decimals.) V =____v M = ___m
