What is the mass of a trolley moving when braking with an acceleration of 0.2m / s², under the action of a force of 40 N.
| August 4, 2021 | education
According to Newton’s second law:
F = m * a, where F is the braking force of the trolley (F = 40 N), m is the mass of the trolley (kg), and is the acceleration of the trolley (a = 0.2 m / s²).
Let’s express and calculate the mass of the trolley:
m = F / a = 40 / 0.2 = 200 kg.
Answer: The mass of the trolley is 200 kg.
