collision? A 50-kg cart moving at 100 km/h collides head-on with an approaching 50-kg cart moving at 10 km/h (in the opposite direction). If the two carts stick together‚ what will be their speed? A 30-kg girl and a 50-kg boy face each other on friction-free roller skates. The girl pushes the boy‚ who moves away at a speed of 3 m/s. What is the girl’s speed? A 70-kg free-floating astronaut fires 0.10-kg of gas at a speed of 30 m/s from her propulsion pistol. What is the astronaut’s recoil speed

LOW COST HILL ASCENT ROLL-BACK UNIT FOR CARS-A NOVEL APPROACH Abstract Every year‚ majority of the accidents that happen in hills is due to stalling of cars and inefficient braking. Stalling of cars happens due to irregular clutch handling and leads to sudden engine failure. Stalling may be very dangerous for cars especially on hilly terrain. These consequences can be avoided by the usage of cars with advanced adaptive braking system. However‚ cars which have advanced adaptive braking system

problem turns out to be s=0.4R‚ so you would strike the ball a little less than half of the radius above the center line. Friction is a huge factor when considering the game of soccer. When a soccer ball is moving along the field there is constantly a frictional force working in the opposite direction of the balls movement. There is an equation that can be used to find the friction force

the demonstrator. Laminar flow turns to be turbulent when the Reynolds Number goes above a certain value‚ around 2000. Aims To look at how the pressure drop changes when the average velocity is altered in a circular pipe and to plot a graph of Friction Factor versus Reynolds Number. Another aim is to examine the shift from laminar flow to turbulent flow.

have similarities. Because both sides are so similar‚ they fail to acknowledge the fact that war is not needed; the bitter feelings toward war in which they both possess are the very feelings that keep them at war. The parties’ comparisons create friction‚ which in turn "rends" them "by war." Lincoln appeals to authority by repeatedly referring to God. Lincoln suggests that the two sides are very similar because they both believe in the same higher power. Since both parties believe in the same higher
