Question
Mr. Hermans is training by swinging a 5 kg kettlebell over his head with a horizontal force of 40 N with air resistance of 8 N opposing the motion. Calculate the net force then find the acceleration of the kettlebell.

The net force can be found by subtracting the force of air resistance from the applied force:
Net force = 40 N - 8 N
Net force = 32 N
To find the acceleration, we can use the equation:
Net force = mass x acceleration
We already know the net force, and the mass of the kettlebell is given as 5 kg, so we can rearrange the equation to solve for acceleration:
acceleration = net force / mass
acceleration = 32 N / 5 kg
acceleration = 6.4 m/s^2
Therefore, the acceleration of the kettlebell is 6.4 m/s^2.
Net force = 40 N - 8 N
Net force = 32 N
To find the acceleration, we can use the equation:
Net force = mass x acceleration
