Answer:
The coefficient of friction is 0.05
Explanation:
Given that,
When Isabella pushes a box of mass 5.25 kilograms with a force of 15.7 newtons.
It accelerates by a rate of 2.50 m/s²
Let coefficient of friction be μ
Force (F) = 15.7 N
Acceleration (a) = 2.5 m/s²
Mass (m) = 5.25 kg
Gravity (g) = 9.8 m/s²
Balanced equation of box to move
F - μmg = ma
15.7 - μ(5.25)(9.8) = (5.25)(2.50)
Hence, The coefficient of friction is 0.05
