2. You want to estimate from how high if it is safe to jump onto a concrete floor. For this, you consider impulse and the force of impact. If you jump from a chair of height of 0.50 m, and land on a concrete floor with stiff legs, it just starts to hurt. Therefore, you consider the average force on your body in such a landing to be your ‘safe limit’. In this case, you estimate that your body moves by about 0.75 cm during the landing. If you allow yourself to bend your knees upon landing on the same concrete floor, you are able to mitigate the force of impact. You estimate that, when bending your knees during landing, your body moves by about a foot, or 0.30 m. For the purpose of this exercise, you consider yourself with a mass of 60 kg.Given the estimates made above, from how high can you safely jump onto a concrete floor?
Two identical objects in outer space have a head-on collision & stick together. If, before the collision, one had been moving at 2 m/s & the other at 1 m/s in the opposite direction, their combined speed after the collision would be ... a) 1.0 m/s. b) 0.67 m/s. c) 0.5 m/s. d) 0.33 m/s. e) none of these.
true or false: 1. during an explosion, the total kinetic energy is always conserved 2. An impulse always goes in the same direction as the applied force. 3. during an explosion of an object the sum of the momentum of all fragments is equal to the momentum of the object before the explosion 4. The momentum of a system is always conserved even if an external force acts on the system. 5. Momentum is a vector quantity during a perfectly inelastic collision between two masses the two masses rebound after the collision.
4. In a perfectly inelastic collision, two objects collide and stick together. Is momentum conserved in the collision? Is energy conserved? Why or why not?

1a)A 4.50 kg ball rolling north at 5.00 m/s collides with a 2.50 kg ball rolling south at 3.00m/s. If the collision is elastic, set up the equations you would solve to determine how fast is each ball moving after the collision. 1b)If the collision between the two balls in question (1a) instead results in both balls sticking together as one, what will their resulting velocity be?
