At what speed does a trolley weighing 500 g roll if its impulse is 4 kg * m / s?
| May 9, 2021 | education
The trolley impulse can be calculated using the formula:
P = m * V, where P is the trolley impulse (P = 4 kg * m / s), m is the trolley mass (m = 500 g = 0.5 kg), V is the required trolley speed (m / s).
Let us express and calculate the speed of the trolley:
V = P / m = 4 / 0.5 = 8 m / s.
Answer: The speed of the trolley is 8 m / s.
