<br><br>
Calculate the resultant force acting on the trolley.
<br>
Use the equation:
<br>
resultant force = mass × acceleration
When the total mass of the trolley was 1.5 kg, the acceleration of the trolley was 0.62 m/s².
<br><br>
Calculate the resultant force acting on the trolley.
<br>
Use the equation:
<br>
resultant force = mass × acceleration
How to approach this question
1. Identify the values for mass and acceleration from the question.
2. Substitute these values into the given equation.
3. Calculate the result and include the correct units.
Full Answer
The question provides the equation: resultant force = mass × acceleration.
It also gives the values:
mass = 1.5 kg
acceleration = 0.62 m/s²
Substitute the values into the equation:
Resultant force = 1.5 × 0.62
Resultant force = 0.93 N
The unit for force is Newtons (N).
Common mistakes
✗ Mixing up the values for mass and acceleration.\n✗ Forgetting the units (N) for force.\n✗ Calculation error.
