Question

Your shopping cart has a mass of 65 kilograms. In order to 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?

Answer 1

Given,
Mass of shopping cart, m = 65 kg
Required Acceleration, a = 0.3 m/s²

We have to find,
Force exerted on the cart, F

Now, we know that,
Force = the product of an object's mass and it's acceleration, i.e.,

$F = ma$
So, assigning the value of "m" and "a" from the question, we get,

$F = 65 \times 0.3$
$= > F = 19.5$
Hence, to accelerate a shopping cart of mass 65 kg down an aisle with an acceleration of 0.3 m/s², we will require a Force of 19.5 kgm/s² or 19.5 N.

That's your answer.

Hope it'll help.. :-D
