Answer: 0.78m/s^2
Explanation:
Force is the product of mass of an object and its acceleration.
i.e Force = Mass x Acceleration
In this case,
Force applied on cart = 35N
Mass of cart and contents = 45Kg
Acceleration = ?
Then, Force = Mass x Acceleration
35N = 45Kg x Acceleration
Acceleration = (35N/45kg)
Acceleration = 0.78 m/s^2 (The unit of acceleration is metre per second square)
Thus, the shopping cart moved with an accelerations of 0.78m/s^2
