An acrobat mass 55 kg is going by her teeth from a metal steel wire that has an unstretched length of 1.5 meter and diameter 1.66 mm. determine the stretch of steel wire

If the speed of a particle triples ,by what factor does its kinetic energy increase?

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?
