A shopping cart accelerates 0.5 m/s2 when a net force of 8 N is applied to it. What is the mass of the shopping cart?
4 kg
0.06 kg
8.5 kg
16 kg
I dont know how to do this
mass = force / acceleration
do i divide or multiply
is it 16?
Yep
To find the mass of the shopping cart, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.
The formula for Newton's second law is:
F = m * a
Where:
F is the net force applied to the object,
m is the mass of the object, and
a is the acceleration of the object.
In this problem, we are given the acceleration (a = 0.5 m/s^2) and the net force (F = 8 N), and we need to find the mass (m).
Rearranging the formula, we get:
m = F / a
Plugging in the given values:
m = 8 N / 0.5 m/s^2
Now, divide 8 N by 0.5 m/s^2 to get the mass:
m = 16 kg
Therefore, the mass of the shopping cart is 16 kg.
