Final answer:
The momentum of a ball weighing 3.4 N and thrown at a velocity of 52 m/s is calculated as approximately 18.0 kg·m/s after determining its mass from its weight.
Step-by-step explanation:
To calculate the momentum of an object, we use the formula P = m × v, where P is momentum, m is mass, and v is velocity. Since the weight of the ball is given, we can calculate the mass by dividing weight by the acceleration due to gravity (g = 9.8 m/s2). The mass (m) of the ball weighing 3.4 N is m = 3.4 N / 9.8 m/s2 = 0.347 kg (approximately).
The ball's velocity (v) is given as 52 m/s. Thus, the ball's momentum is then P = 0.347 kg × 52 m/s = 18.044 kg·m/s, which we can round off to 18.0 kg·m/s for simplicity.
