Answer:
Explanation:
a is the acceleration
μ is the coefficient of friction
Acceleration of the object is given by
Velocity at the bottom
after travelling 4m , its velocity becomes 0
Coefficient of kinetic friction
μ = F/N
Therefore, the Coefficient of kinetic friction is 0.31

The ONLY way to change the volume of a sample of gas is to transfer it to a container with different volume.
Simply changing its temperature or pressure in the same jar won't do it. Any amount of gas always fills whatever container you keep it in.
Answer:
the acceleration is 130.3m/s²
Explanation:
Given data
Force F= 18.9N
Mass of ball m= 0.145kg
Acceleration a=?
Applying the Newton's second law of motion
"The rate of change of momentum of a body is proportional to the external force".
F=ma
a= F/m
a= 18.9/0.142
a= 130.3m/s²
