Answer:
To calculate the force required to give the trolley a specific acceleration, you can use Newton's second law of motion:
F=m⋅a
Step-by-step explanation:
Where:
�
F is the force applied (in newtons, N)
�
m is the mass of the trolley (in kilograms, kg)
�
a is the acceleration (in meters per second squared, m/s²)
In your case, the mass of the trolley is
�
=
5
kg
m=5kg and the desired acceleration is
�
=
2
m/s
2
a=2m/s
2
.
Plugging these values into the formula:
�
=
5
kg
⋅
2
m/s
2
=
10
N
F=5kg⋅2m/s
2
=10N
Therefore, the shopper should apply a force of 10 newtons in order to give the trolley an acceleration of
2
m/s

2m/s
