Aroller coaster speeds up with constant acceleration for 2.3 s until it reaches a velocity of 35 m/s. during this time, the roller coaster travels 41m. what is the initial velocity of the roller coaster before it begins to accelerate?

in physics zero. in muscle fatigue could be high

volts times amps 6 x 0.5 3w

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
