To find the mass of the child, we can use Newton's second law of motion which states:
F = m * a
Where:
F = net force (66 N)
m = mass (unknown)
a = acceleration (2.0 m/s^2)
So, we can rearrange the formula to solve for mass:
m = F / a
m = 66 N / 2.0 m/s^2
m = 33 kg
Therefore, the mass of the child is 33 kg.
A net force of 66 newtons accelerates a child at 2.0 m/s2 down a smooth playground slide. What is the mass of the child?
