A student investigated how changing the mass of a trolley affects its acceleration.
For one setup, the student recorded three values for the acceleration of the trolley:
2.42 m/s2,2.47 m/s2,2.43 m/s2 2.42\text{ m/s}^2, \quad 2.47\text{ m/s}^2, \quad 2.43\text{ m/s}^2 2.42 m/s2,2.47 m/s2,2.43 m/s2Calculate the mean acceleration of the trolley.
When the total mass of the trolley was 1.8 kg1.8\text{ kg}1.8 kg, the acceleration of the trolley was 1.35 m/s21.35\text{ m/s}^21.35 m/s2.
Calculate the resultant force acting on the trolley. Use the equation:
resultant force=mass×acceleration \text{resultant force} = \text{mass} \times \text{acceleration} resultant force=mass×acceleration
