1.) This person
exerts a net
force on their
shopping cart of
35 N. The total mass of the
cart and contents it 45 kg.
Calculate its acceleration.

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
