Un objeto de 100 kilogramos de masa se encuentra en una superficie lisa plana y completamente horizontal, y una fuerza de 100 newtons lo empuja de izquierda a derecha , y otra fuerza del mismo valor lo empuja de derecha a izquierda. ¿hacia dónde se moverá el cuerpo?.

20. threshold braking in the vehicle's braking system occurs when a. the brake pedal is pushed, heel on floorboard, with full foot pressure. b. the brakes are exerting full braking power, without traction loss. c. the driver begins pushing down the brake pedal, with moderate slowdown. d. the brakes just begin to take hold with a gradual slowdown.

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid
