In the equation F=m⋅v2rF=m⋅v2r find the value of m when F = 590, v = 34, and r = 17.

F = m*ac = m*V^2/r
m = F*r/(V^2) = 590*17/34^2 = 8.68 kg

Given,

Force (F) = 590 N

Velocity (V) = 34 m/sec²

Radius (r) = 17m

We know that:-

Force (F) = mv² / r

→ (F x r) = mv²

→ mass (m) = (F x r) / v² = 590 N x 17M / (34 m/sec)²

= 10030 / 1156 = 8.67 kg

∴ mass (m) = 8.67 kg.

F = (mv^2)/r

Fr = mv^2

m = Fr/v^2

= (590 * 17)/34^2

= 8.676470588

= 8.68 kg (2 dp)
