A 400g soccer ball was reported to have a speed of 5ms on a penalty kick. What was the impulse of the ball at the same time.
To find the momentum of a soccer ball, acquired by him after taking a penalty, we use the formula: P = m * V.
Variables: m is the mass of a soccer ball (m = 400 g = 0.4 kg); V is the speed acquired by the ball (V = 5 m / s).
Calculation: P = m * V = 0.4 * 5 = 2 kg * m / s.
Answer: After the penalty was taken, the impulse of the soccer ball became equal to 2 kg * m / s.
