A dancer lifts his partner above his head with an acceleration of 2.5 m/s squared the dancer. Exerts a force of 200N what is the mass of the partner

Respuesta :

F = ma
F = 200N, a = 2.5m/s^2

200N = (2.5)m
m = 80kg

Answer:

mass = 80 kg

Explanation:

As per Newton's II law we know that

[tex]F = ma[/tex]

here we know that

[tex]F = 200 N[/tex]

also we know that

[tex]a = 2.5 m/s^2[/tex]

so from above formula we have

[tex]200 = m(2.5)[/tex]

[tex]m = \frac{200}{2.5}[/tex]

[tex]m = 80 kg[/tex]
