A car is traveling east at an unknown Initial velocity. Without changing directions, it accelerates at 0.75 m/s2 for a distance of 300 m, increasing its velocity to 30 m/s. What was the Initial velocity of the car?

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

Física: un futbolista patea hacia el arco con una velocidad de 15m/ah, calcular: a)el alcance para un ángulo de tiro de 25º, b) el tiempo que el balón permanece en el aire.

The first-order reaction a→2b+c has rate constant 0.538 s−1. if the initial concentration of a is 0.867 mol l−1, what is the half-life of the reaction in seconds? remember to use correct significant figures in your answer (round your answer to the nearest hundredth). do not include units in your response.
