Un bloque con masa de 0.5 kg viaja con una rapidez de 2.0 m/s en la dirección X positiva sobre una superficie plana sin fricción. Al pasar por el origen, el bloque experimenta durante 1.5 segundos una fuerza constante de 3.0 newtons que forma un ángulo de 60 con respecto al eje X ¿que velocidad tiene el bloque al término de ese lapso?

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
