Professional Application - One hazard of space travel is debris left by previous missions. There are several thousand objects orbiting Earth that are large enough to be detected by radar, but there are far greater numbers of very small objects, such as flakes of paint. Calculate the force exerted by a 0.100-mg chip of paint that strikes a spacecraft window at a relative speed of 4.00X10 m/s, given the collision lasts 6.00X10 s.

A 980-kg sports car collides into the rear end of a 2500-kgkg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.9 mm before stopping. The police officer, estimating the coefficient of kinetic friction between tires and road to be 0.80, calculates the speed of the sports car at impact. Question: What was the speed sports car at impact? v=??

Problem 3: Doctor Doom, who has a mass of 188kg, is charging towards the Hulk who has a mass of 636kg and is running at him with a velocity of -33.0m/s. The two of the undergo an elastic collision and Doctor Doom ends up flying away from the Hulk with a final velocity of -61.0m/s. a) What is the initial velocity of Doctor Doom and the final velocity of the Hulk? b) What is the initial kinetic energy of Doctor Doom and the Hulk before they collide?

Canon and Lucas are playing beach volleyball. Canon spikes the 240 g ball toward Lucas at 8.5 m/s. Lucas deflects the ball by hitting it with -87.5 N of impact force for a 0.006 s impact. Assuming only one dimension of motion, what is the magnitude of the velocity of the ball after it is hit by Lucas?

lease answer the following question(s): 1. Two manned satellites approach one another at a relative speed of 0.29 m/s, intending to dock. The first has a mass of 4.0x 10³ kg, and the second a mass of 7.5x10³ kg. If the two satellites collide elastically rather than dock, what is their final relative velocity? Final relative velocity = ✔m/s Submit Answer see other options - If you don't want to answer the question right now View Forum Activities (0 new of 0) Powered by CogBooks ▬▬ Search fs 10 Answering the question(s) helps us recommend your next activity. f6 99+

I.  A lump of clay (m = 3.01 kg) is thrown towards a wall at speed v = 3.15 m/s.  The lump sticks to the wall.  (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   II.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.15 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   III.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 2.24 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic…

Q.20. As given in the figure, the surface is friction less. The two objects collide, stick together and move together after the collision. Find the magnitude of final velocity in m/s? (write numerical value only) m, =3 Kg Vi =8m/s m = +kg Syu8 = Vz =10m/s Me

Problem B) An inelastic collision occurs between a particle of mass 1.5 kg moving with an initial velocity of v = (-2i – 1.33 + 0.7k) m/s and another particle of mass 0.8 kg that has an initial velocity of v = (5.6å + 0.53 + 4.3k) m/s. What is the final velocity of the particles in unit vector notation? %3D
