Question

A dancer lifts his partner above his head with an acceleration of 2.5 m/s2. The dancer exerts a force of 200 N. What is the mass of the partner?

Answer 1

Super helpful formula in physics:
Force = acceleration * mass
F = am
Remember your F=am!

mass = Force/acceleration
mass = 200 N / (2.5 meters/seconds^2)
mass = 80 kilograms (about the mass of an average person)
