Explanation:
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?
The mass of the partner can be calculated from
F = m*(g+a). , where g is the gravity acceleration, the a = 2,5 m/s^2, F = 200 N
as
m = F/(g+a) = 200/(9,81+2.5) = 16.247 [kg]
Hope it helps.
