Question

how much force would you need to use in order to accelerate an 80k shopping cart to 0.2 m/s^2 (F=ma)

A) 16N

B) 400kg

C) 400N

D) 16kg

Answer 1

Correct answer is 16 N.

Explanation:

Given data:

Mass of the shopping cart be m = 80 kg

Acceleration of shopping cart be a = $0.2 m/s^2$

Let the force need to be is F.

Write the expression for force $F = m*a$

Substitute the values in the above equation.

$F = 80 * 0.2\\ =16 kg. m/s^2 \\= 16 N$

Hence, the correct answer is 16 N (option A).
