Your shopping cart has mass of 65 kg. in order of accelerate the shopping cart down an aisle at 0.3 m/sec^2, what force would you need to use or apply to the cart?

Fnet = m x a
= 65kg x 0.3m/s^2
= 19.5N
This is assuming that there is no friction or other external forces!

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
