An object accelerates at 7.5m/s^2 with a force of 25N west being applied to it and there is a frictional force of 13N. What is the mass of the object
net force= m*a
25-13=m(7.5) solve for mass m.
To find the mass of the object, you can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The mathematical equation for Newton's second law is:
F_net = m * a
Where F_net represents the net force, m represents the mass of the object, and a represents the acceleration.
In this scenario, the net force is the force being applied minus the frictional force:
F_net = Force_applied - Force_friction
Substituting the given values:
F_net = 25N - 13N = 12N
Now we can rearrange the equation to solve for the mass (m):
m = F_net / a
Substituting the given values:
m = 12N / 7.5 m/s^2
Calculating:
m = 1.6 kg
Therefore, the mass of the object is 1.6 kilograms.
